AI and Elections: How Well Do AI Platforms Answer Voter Questions?

A States United study before the 2026 midterms finds that ChatGPT and Google AI offer incomplete and inconsistent responses to common voter questions, even as the accuracy of AI platforms improves.

Issue Areas

Artificial intelligence (AI) platforms are now part of the information landscape that voters use to navigate elections. During the 2026 midterms, millions of Americans are likely to ask AI platforms questions about how to participate in the voting process.

To understand how voters are served when they ask AI platforms about elections, States United conducted an empirical study of two of the most commonly used platforms, ChatGPT and Google AI. Our research tested for two criteria. First, we examined how well AI platforms answer election questions that voters routinely ask—about voter registration, voting locations, primary and general election dates, mail voting, candidates running for office, and how election results are counted. Second, we analyzed whether these platforms reliably direct voters to their state’s official election website. State election officials are responsible for providing accurate and reliable election information. Their websites are important, authoritative sources for voters.

Across two rounds of empirical testing in late 2025 and early 2026, our research found that while AI platforms have demonstrated improved accuracy over time, they are incomplete substitutes for official election information; inconsistent in directing voters to authoritative state sources; and vulnerable to format changes driven, in part, by commercial pressure.

Five key findings emerged:

  • Improved accuracy over time. In the first preliminary round, the error rate for responses from Google AI and ChatGPT was 6.9% and 8.2%, respectively. In the second primary round, the rate of verifiable factual errors fell to 0% across both platforms. The accuracy of responses from the AI platforms improved. However, the chatbot responses did not provide everything a voter needs to know. Our finding of improved accuracy comes with a caveat: technically accurate responses were often incomplete, failing to direct voters to official sources that would further enable their participation. Responses with an improved 0% error rate still came with information gaps, such that the improvements were not always complete, current, or usable.
  • Inconsistent direction of voters to official state websites. The single most important measure of voter utility examined in this study was whether AI platforms directed voters to their state’s official election website. AI platforms guided voters to state websites less than 50% of the time, and for some questions, they almost never did. ChatGPT mentioned a state election site in 39.4% of its responses, and Google AI did so in 55.6% of its responses.
  • Incomplete answers about candidate listings. When asked who is running for a particular office, AI platforms produced incomplete answers at strikingly high rates, the most of any question type. ChatGPT returned incomplete candidate lists for 88.9% of the gubernatorial queries. Arizona, with its large and actively changing candidate field, drove most of the incompleteness. But in this study, AI systems trained on historical data and reliant on periodic retrieval were structurally ill-suited to track real-time candidate filings.
  • Overreliance on Wikipedia for election information sourcing. Wikipedia accounted for 12.3% of all 3,481 cited links across the primary study and dominated the sourcing of candidate questions. This finding is a meaningful concern given that Wikipedia is openly editable and not authoritative for time-sensitive or jurisdiction-specific election information.
  • Vulnerability to format changes. Google AI changed its output format in the course of the study, replacing written summaries with lists of links. The links-only responses, beginning on or around Feb. 2, 2026, offered no prose, guidance, or consistent recommendations to visit official state sources. This change was applied unevenly across query topics and appeared more pronounced for election-related queries than others. When asked why its output changed, Google AI attributed the change to efforts to improve accuracy and reduce hallucinations, while also describing the change as part of making AI search more monetizable.

Our preliminary investigation, in September and October 2025, collected 497 responses (216 from Google AI and 281 from ChatGPT) across six states (Arizona, Michigan, North Carolina, Nevada, Pennsylvania, and Wisconsin). The following primary investigation, in January and February 2026, collected 402 responses across Arizona, Michigan, and Pennsylvania under three platform conditions: a free user subscription to ChatGPT, Google AI in an incognito session, and Google AI accessed through an account with a history of election-skeptic browsing. See Methodology for more details.

The bottom line—based on two rounds of empirical research and every platform condition tested—is that voters seeking election information on leading AI platforms are inconsistently directed to the authoritative information on their state’s official election website. Although AI tools are advancing, they should be seen as a complement to, rather than a replacement for, official voter information.

A complete list of recommendations on how voters, election officials, and AI platform operators can apply these findings is included at the end of this report.

Introduction

A healthy democracy depends on voters having accurate, accessible, and complete information on how to participate. In 2026, this information is increasingly delivered by artificial intelligence (AI). Americans now routinely ask AI platforms questions they once would have asked a librarian, an election office, or a search engine: How do I register to vote? When is the primary? Where is my polling place? Who is on the ballot for governor?

AI-generated election information is not new, but the rate at which voters rely on AI to navigate the electoral process is. A June 2026 Pew Research Center survey found that about half of U.S. adults now use AI chatbots, up from a third in 2024, and that roughly a quarter use them daily. About four in 10 adults say they use chatbots to search for information. These searches increasingly include inquiries about elections. A July 2026 article in The New York Times predicts that “the 2026 midterms may be the first American elections in which voters are using A.I. in meaningful numbers.” While the convenience of consulting a chatbot for voting information is evident, this approach comes with risks, too.

Election rules in the United States vary across all 50 states and thousands of local jurisdictions. Registration deadlines, mail ballot procedures, polling locations, and candidate fields are not standard national facts; they are state-, county-, and precinct-specific details that change with every election cycle. A voter who relies on an AI platform that returns the wrong year, wrong state, or outdated source can miss a deadline, submit an incomplete application, or arrive at the wrong polling location.

These risks are unfolding in an information environment already shaped by widespread election misinformation, declining public trust, and rapidly evolving platform behaviors. In the early months of 2026, a study commissioned by The New York Times revealed that the Google AI Overview frequently produced unsupported answers, referencing sources that did not actually back the assertions made, with error rates ranging from 37% to 56%, depending on the specific model used. Notably, that study examined general-purpose queries rather than election-specific ones, but its findings should serve as a warning for the millions of voters now turning to AI for information about how to register, where to vote, and what is on their ballot. If AI platforms regularly cite sources that do not support their claims when the stakes are ordinary, the risks compound when the stakes concern the right to vote.

We tested ChatGPT and Google AI Overview because they are the two AI products that a voter is most likely to encounter. ChatGPT is the most widely used chatbot in America: 44% of adults report using it, according to Pew Research Center, far outpacing every other chatbot Pew tested. Google AI Overview, meanwhile, features prominently on the most-used search engine in the country, appearing before voters every time they perform a Google search. Because Google AI Overview sits at the top of ordinary Google search results, a voter encounters the AI product without choosing to open a chatbot at all, and 60% of U.S. adults say they read the AI summaries that appear above their search results. By testing the most-used standalone chatbot (ChatGPT) alongside the AI layer built into the most-used search engine (Google AI Overview), this study approximates what a typical voter actually sees when asking an AI platform about an election.

Our recommendation that voters consult their state’s official election website rests on who maintains those sites. Elections in the U.S. are run by the states. Secretaries of state and other chief election officials, together with county and municipal clerks, set election procedures, maintain voter registration databases, produce voter education materials, administer mail voting, and certify results. The office that publishes a registration deadline is the same office that administers it, which is why a change appears there first. State sites are not uniform in quality across the 50 states, and officials do occasionally update material. But no other category of source carries the same legal responsibility for the accuracy of what it publishes about a voter’s own jurisdiction.

The findings that follow are intended to help voters, election officials, and AI platform operators understand both what AI does well and where it falls short.

Key Findings

Two rounds of testing were conducted. The first was a preliminary study, conducted in September and October 2025, with 216 Google AI responses and 281 ChatGPT responses from six states. In January and February 2026, the second primary wave of the study was conducted, gathering 402 responses from Arizona (134), Michigan (134), Pennsylvania (115), and unspecified state questions (19) across three platform conditions. Five important findings emerged from these tests that voters and election officials should know. In short, AI platforms have improved in accuracy, but accuracy is not the same as adequacy. AI still struggles with questions regarding voting.

Finding 1. AI is more accurate. Being accurate is not the same as being adequate.

Across both ChatGPT and Google AI, the factual accuracy improved meaningfully between rounds. In the preliminary investigation, 6.9% and 8.2% of the responses from Google AI and ChatGPT, respectively, contained verifiable factual errors. In the primary investigation, conducted several months after the preliminary investigation, no responses across any platform conditions were coded as inaccurate. This is real progress and should be acknowledged.

However, accuracy alone does not determine whether a voter is well served. Our coding tested whether discrete factual claims, such as a registration deadline, primary date, and procedural steps, could be verified against official state election sources. But findings from the primary investigation show that AI platforms simultaneously can return technically accurate responses yet leave voters without the necessary information or pathway to participation. For example, the investigation yielded scenarios in which a voter asks about registration and receives correct procedural guidance but is never directed to the state election website where they can complete that registration. The information may be accurate, but not adequate in addressing that voter’s needs.

It is worth being precise about what a 0% error rate does and does not establish. It means that for the questions we tested, we found no verifiable factual claim to be wrong. It does not mean, however, that the responses were complete: ChatGPT returned incomplete candidate lists in 88.9% of gubernatorial queries. A 0% error rate also does not mean voters were reliably pointed to the office that could confirm the answer: ChatGPT mentioned a state election site in 39.4% of its responses, and after Google changed its output format, Google AI did so in none of its responses. And it does not mean the results hold beyond the conditions we tested, since we asked a defined set of questions in round two about three states over a period of weeks. The improvement in accuracy is real; however, it does not make them ready to serve as a voter’s primary source for election information.

Figure 1. Inaccuracy rate (% of responses with verifiable errors) by platform and round.

Finding 2. AI platforms inconsistently direct voters to their state’s official election website.

Whether AI platforms direct voters to their state’s official election website is the single most important measure of voter utility examined in this study. State election websites are maintained by the election officials who administer the process, and they are updated as rules, deadlines, and candidate filings change. They are the source best positioned to give voters the deadlines, polling places, and candidate filings that apply to them, because the office publishing the information is responsible for it. According to our data, AI platforms guide voters to these sites less than 50% of the time, and for some questions, they almost never do so.

When AI generated explanatory text, its behavior on the polling location question stood apart from its behavior on every other voter question we tested. ChatGPT mentioned a state election site in 88.2% of polling location responses (82.4% provided a direct link), but only 33.6% of responses to the other questions (31.5% direct link). Google AI (Incognito) summaries mentioned a state site in 100% of polling location responses (66.7% direct link), but only 50% of responses to other questions (26.4% direct link). After Google’s mid-study format change, both Google AI conditions dropped to 0% on both metrics across every question type, including polling, because links-only responses contain no explanatory text in which a state site can be recommended.

Figure 2. Percentage of responses that mentioned a state election site or provided a direct state-site URL by platform condition. Percentages may not sum to 100% due to rounding.

Unlike the other questions, the polling location question—“where is my closest polling location in [state]?”—produced near-universal referral rates. The reason for the high referral rate to state election sites is structural in nature. No AI platform can know a voter’s address and cross-reference it with precinct maps in real time. The only responsible answer is to send the voter to the official state lookup tool. The platforms refer users to state election sites because they have no other choice. The challenge is replicating that behavior on other election-related questions.

Finding 3. Candidate questions exposed a structural weakness that AI cannot easily fix.

When voters asked who was running for a particular office, AI platforms produced incomplete answers at strikingly high rates. ChatGPT returned an incomplete list of declared candidates in 88.9% of the gubernatorial candidate queries, 35.7% of the attorney general queries, and 28.6% of the secretary of state queries. Google AI (Incognito) summary responses showed a 44.4% incompleteness rate on governor and 42.9% on both attorney general and secretary of state queries. These are not failures of accuracy in the traditional sense because the AI identified real candidates. However, the problem was that the platforms did not name all of them.

 

Figure 3. Percentage of candidate responses coded as incomplete by office and platform. Text-summary responses only.

Arizona drove most of the incompleteness. Among the text-summary responses, Arizona gubernatorial responses were incomplete in 100% of the cases, compared to 77.8% for Michigan and 44.4% for Pennsylvania. Responses to questions about Arizona’s secretary of state race returned incomplete results 66.7% of the time, compared to 11.1% for Michigan. Arizona attorney general (AG) responses were incomplete in 77.8% of cases, compared with 11.1% for Michigan. Arizona’s 2026 gubernatorial race features at least nine (at the time of the primary study) declared candidates across multiple parties, with filings still ongoing during the data collection period; the AG race featured a similarly active and evolving field. AI platforms trained on historical data and relying on periodic web retrieval are not designed to track the filing activity of multiple candidate-filing deadlines and primaries in real time.

Figure 4. Percentage of candidate responses coded as incomplete by office and state. Text-summary responses only.

This is a structural limitation, not a temporary one. Candidate fields are unique across states and change with every filing deadline, withdrawal, and announcement. AI systems that retrieve information periodically rather than continuously will continue to lag the actual ballot. Compounding the problem: When AI answered candidate questions, it relied heavily on Wikipedia (see Finding 4) rather than on official state candidate filing records. Direct state election site links were provided in 0% of candidate responses across nearly all conditions tested. This means that if voters ask AI who was running, they will rarely be pointed to the place that would tell them definitively.

Finding 4. AI platforms frequently cite sources voters cannot easily evaluate.

Across the primary study, AI platforms cited 3,481 links in total. State and local government sources accounted for the largest share (1,445 combined links, or 41.5%) and trustworthy non-profits for the next largest (822 links, or 23.6%). The remaining 35% of links are where the analytical concern lies. Wikipedia alone accounted for 429 of those sources, representing 12.3% of all the links and was the most heavily relied-upon source for candidate questions specifically. The Mixed and Unreliable category includes mixed-content platforms like Reddit, YouTube, and other third-party sites that are not vetted by election officials, accounting for another 264 links, or 7.6%. Taken together, Wikipedia and Mixed and Unreliable sources made up roughly one in five links that AI platforms surfaced when voters asked election questions.

Figure 5. Distribution of all cited links in the primary study by source type (n=3,481 links).

What these two categories share is that voters cannot reliably evaluate the content on the other end of the click. Wikipedia is broadly accurate on many topics, but it is openly editable and the qualifications of contributors cannot be verified, and entries on time-sensitive subjects such as filing deadlines, candidate lists, polling procedures, ballot-counting rules may lag official sources or contain errors volunteer editors have not yet caught. Mixed-content platforms have a different problem: State election officials post verified informational videos to YouTube and answer voter questions on Reddit, but so do individuals spreading election mis- and disinformation, and an AI response that points a voter to either platform gives no indication which is which. When a voter sees a YouTube link in an AI-generated answer, they have no way of knowing whether the destination is a secretary of state’s verified channel or an unverifiable creator. ChatGPT’s candidate-question responses make the problem concrete: ChatGPT averaged 5.61 Wikipedia links per gubernatorial response and 6.4–6.8 per secretary of state and attorney general response, the highest Wikipedia reliance of any question type by a wide margin.

AI platforms can produce responses that look comprehensively sourced with many cited links, drawn from many different domains while routing a meaningful share of voters to destinations that cannot be trusted to provide accurate, current, jurisdiction-specific election information. The volume of plausible sources is not the same as the presence of credible ones.

Finding 5. Google AI changed its output format mid-study, and election queries lost their explanatory text.

On or around Feb. 2, 2026, mid-data collection, Google AI began returning only links to election-related queries in the incognito condition. Specifically, it replaced the written summaries it had been generating up to that point and moved to providing a simple list of sources telling users, “Here are top web results for exploring this topic.” An example of the output list is provided in Screenshot 1, below, and this change is unmistakable in the data. Pre-change incognito responses (collected Jan. 28 to 30) averaged 224.5 words per response. From Feb. 2 onward, a substantial share of incognito responses dropped to nine words, reflecting nothing more than the link list. All 79 responses collected via the election-skeptic profile (Feb. 2 to 26) returned links-only output without exception.

Screenshot 1. Example of the Links-only Response by Google AI

The transition was not clean. Incognito responses on certain later dates, notably Feb. 10 to 12 and Feb. 19, returned to summary form before reverting again to links-only output, suggesting that Google was actively adjusting the rollout. This change did not appear to apply uniformly across query topics. Spot checks during the study period suggested that non-election queries continued to receive summary-style responses on the same days when election queries returned links-only output. If that pattern reflects Google’s design choices rather than incidental variation, it raises an additional concern: Election-related queries may receive a less informative format than other categories of questions being routed through the same system.

Figure 6. Average number of words per response by platform condition. Google AI links-only responses (post-format change) were flattened to a fixed nine words, reflecting only link text with no generated prose.

The drop in word count, however, does not mean Google AI was providing voters with less information by every measure. As Figure 7 shows, the average number of links per response did not fall after the format change, it rose. Pre-change Google AI summaries cited an average of 3.7 sources per response. Post-change links-only responses cited an average of 9.6 sources, comparable to ChatGPT’s 10.2. What the format change removed was not the underlying source list, but the prose wrapped around it. The explanatory text that helped voters understand which source was most authoritative, what each one contained, and where to start was eliminated, while the volume of clickable destinations increased significantly.

Figure 7. Average Number of Links by Condition

To understand why this change occurred, we asked Google AI. Its response characterized the change as an effort to improve accuracy, reduce hallucinations, and address publisher concerns about AI-generated content, and as part of making AI search more monetizable. The inclusion of monetization in the rationale is notable. Links-only responses send users to third-party websites, which generate click-through traffic and advertising revenue in a way that a self-contained AI summary does not. Whatever the balance of motivations, the practical consequence for voters is direct: The explanatory text that helped voters understand, evaluate, and act on election information is gone. Pre-change Google AI summaries mentioned an official state election site in 55.6% of the responses. After the format change, the figure dropped to 0%. A list of links is not a voter guide.

An Additional Note on Account-Level Personalization

The primary study’s third platform condition, a Google account with an established history of election-skeptic browsing, was designed to test whether account-level personalization meaningfully shapes the election information AI platforms provide. The intent was to compare a personalized account’s responses to those of an unsigned-in incognito session, holding the question set constant. This condition warrants a specific note in this report because of one significant methodological caveat: all 79 responses collected from the election-skeptic profile were captured at or after Google’s Feb. 2, 2026, format change and uniformly returned the links-only output format described in Finding 5.

This means that the available data cannot cleanly separate the effect of account personalization from the effect of format change. The following observations were made. In the source mix, the election-skeptic profile’s responses were broadly comparable to incognito links-only responses: an average of 1.9 state government links per response (versus 1.6 for incognito links-only) and 3.4 trustworthy non-profit links (versus 4.5). Mixed and Unreliable links appeared at modestly higher rates in the election-skeptic profile (an average of 0.8 per response, versus 0.7 for incognito links-only), a small difference in absolute terms, consistent with the broader pattern of source-mix similarity between the two conditions.

Figure 8. Average number of sources per response by Google profile

However, these observations should be interpreted with caution. Source-mix similarity does not equal voter-utility equivalence: Neither links-only condition included explanatory text, mentions of the state election site, or directional guidance, and neither served voters well on the dimension this study most cares about. The data also cannot tell us how the election-skeptic profile would have responded under the pre-change summary format, which is the format in which content choices and framing decisions are most visible to the user. To answer this question, future testing is needed in a context where Google has reverted to or made available a summary format.

Guidance on How to Apply Our Findings

These findings provide practical guidance for voters making decisions about how to participate in the 2026 elections, state and local election officials working to ensure voters have access to accurate information, and AI platform operators whose products are increasingly mediating that access.

Recommendations for voters:

  • Use your state’s official election website as your primary source. AI platforms can help you understand general concepts, but for authoritative information about registration deadlines, polling locations, candidate filings, and ballot procedures, go directly to your state’s official election site. These sites are maintained by election officials and are updated as rules, deadlines, and filings change.
  • Treat AI-generated candidate lists as starting points, not final answers. This study found that candidate questions had the highest incompleteness rates of any question type, and that AI platforms relied heavily on Wikipedia rather than official state candidate filing records. If you are seeking information about who is on the ballot, verify the AI’s response against your state’s official candidate filings.
  • Remember that a list of links is not an answer. Following Google AI’s format change, many election responses now consist of links with little to no explanatory text. Receiving a list of links does not mean that the AI has answered your question. Visit your state’s official election website directly to confirm what you have been told.
  • Don’t confuse confidence in tone with content accuracy. AI platforms can produce authoritative-sounding responses that are nonetheless incomplete, outdated, or sourced from sites that are not designed to keep up with election timelines. A confident-sounding answer is not necessarily reliable.

Recommendations for election officials

  • Optimize official election websites for AI discoverability. Well-structured, mobile-friendly, and search-optimized state election sites are more likely to be surfaced by AI platforms as primary sources of information. Structured data markup, clear plain language content, and consistent URL conventions can improve AI indexing and citation of official resources by AI tools.
  • In future cycles, build voter education around candidate filing windows. This study shows that AI platforms were least complete on candidate questions during the period when the candidate fields in our test states were still forming. As offices plan for future cycles, voter education reminding the public to verify AI-generated candidate lists against official filing records is worth building into the calendar around filing deadlines and ballot certification.
  • Prioritize earned media about election processes and facts. News coverage is a meaningful part of what AI platforms cite. State, local, and national news outlets together accounted for 521 of the 3,481 links in the primary study, or 15%, making news the third-largest source category after government sites and nonpartisan nonprofits. AI systems that retrieve current web content are drawing on the same coverage that election officials help shape. Offices that consistently place election explainers with national, state, and local outlets are adding accurate material to the pool of recent content these systems pull from. This study did not test that pathway directly, so we offer it as a plausible lever rather than a demonstrated one.

Recommendations for AI platform operators

  • Always include a direct link to the relevant state election website. This single design commitment, presented in any output format, including links only, would materially increase the rate at which voters reach authoritative sources of information. It does not depend on the model getting every fact right; it simply ensures that voters are directed to the source that does so.
  • Prioritize state and local government sources for election-related queries. Platforms should default to privileging official election office resources when answering voters’ election-related questions and should promote these sources ahead of Wikipedia and general news media. Wikipedia’s prominence in AI’s candidate question responses is incompatible with the time-sensitivity of those questions.
  • Develop real-time candidate filing integrations. The high incompleteness rates of candidate questions reflect a structural data gap. Partnerships with official election data sources or real-time integrations with state voter registration and candidate filing systems would substantially improve the performance of these rapidly evolving queries.
  • Adopt election banner referrals to nonpartisan voter information services. Platforms can attach a standing referral to election-related queries. These referrals appear as a short banner or module, sitting outside the generated response, that points users to a nonpartisan voter information service. Because the referral is not part of the generated text, it does not depend on the AI platform getting every answer right, and it survives changes in output format. For example, when users ask Anthropic’s Claude assistant about election-related questions, the platform displays a banner directing them to TurboVote, a nonpartisan service operated by Democracy Works that provides accurate jurisdiction-specific information. Other AI platforms should consider similar designs as defaults rather than exceptions.

Screenshot 2. Claude’s Banner Directing Users to a Trustworthy Election Source
  • Be transparent about the commercial incentives shaping output formats. When a platform’s stated rationale for changing how AI answers questions includes the goal of making the product more monetizable, it is a transparent acknowledgment that format decisions are not driven solely by user benefit. Platforms have an obligation to be clear with users when business considerations reshape the information they receive.
Conclusion

AI platforms are now part of the information landscape that voters use to navigate elections. They are powerful and accessible tools. They are also incomplete substitutes for official election information as they are slow in capturing rapidly changing candidate fields, inconsistent in directing voters to authoritative state sources, vulnerable to format changes driven in part by commercial pressure, and potentially shaped by user account history in ways that further testing will need to characterize.

The mid-study Google AI format change documented here offers a cautionary illustration of how civic information can shift abruptly in response to platform-level business decisions and how unevenly such shifts can be applied across query topics. When a company describes its AI changes as designed to make the product more monetizable, and those changes reduce the explanatory guidance available to voters, the tension between commercial incentives and civic information needs is on direct display.

The key source for election details remains the official election website of a voter’s state, which is maintained by the officials who run the election and built to help voters participate. State sites vary in quality and are not immune to error. But they are the closest thing voters have to a reliable, accountable, jurisdiction-specific answer, and every voter, whatever their election question, should be directed there. AI as a tool should help voters identify what questions to ask, but it cannot yet be trusted to answer reliably.

The most reliable source for election details is the official election website of a voter’s state, which is authoritative, current, officially managed, and specifically created to assist voters in participating. Every voter, regardless of their election question, should be directed to the website. AI as a tool should help voters identify what questions to ask, but it cannot yet be trusted to answer reliably.

Methodology

This study employed a systematic content analysis design that involved two rounds of data collection. In both rounds, the researchers submitted standardized election-related questions to ChatGPT and Google AI and coded the resulting responses along multiple dimensions related to accuracy, completeness, content, and source quality. The research design was developed to simulate the experience of a typical voter using an AI platform to obtain election guidance.

Preliminary investigation. This study was conducted between Sept. 5 and 17, 2025 (Google AI), and Oct. 10 and 22, 2025 (ChatGPT), by three researchers across six states: Arizona, Michigan, North Carolina, Nevada, Pennsylvania, and Wisconsin. A total of 216 Google AI and 281 ChatGPT responses were collected, focusing on three foundational voter questions: how to register to vote, when the primary election is, and when the general election is.

Primary investigation. Conducted between January and February 2026 across three states (Arizona, Michigan, and Pennsylvania) under three platform conditions:

  • ChatGPT (Free): The free-tier version of OpenAI’s ChatGPT, providing the most accessible AI option for a typical voter. No account was logged in to prevent any knowledge that the AI has about the user from influencing how the platform responded to questions.
  • Google AI (Incognito): Google AI Overview summary feature accessed via an incognito browser with no Google account signed in, reflecting a neutral, non-personalized session. Specifically, an incognito browser is a private browsing mode that does not carry a signed-in account, browsing history, or prior activity into the session, so it reflects a neutral, non-personalized user.
  • Google AI (Election-Skeptic Profile): Google AI Overview accessed while signed into a Google account with an established history of browsing election-skeptic content. This condition was designed to test whether account-level personalization influenced the content or quality of election-related AI outputs. (We use the term “election-skeptic profile” rather than partisan or movement-specific labels because election skepticism — engagement with content questioning the integrity of recent U.S. elections — is the analytically relevant variable that the condition operationalized.)

A total of 402 observations were collected by two researchers during the primary investigation. Eight standardized question types were used:

  • “How do I get registered to vote in [state]?”
  • “When is the primary election in [state]?”
  • “When is the general election in [state]?”
  • “Where can I vote in [state]?”
  • “Where is my closest polling location in [state]?”
  • “How can I vote by mail in [state]?”
  • “When will I get my mail ballot in [state]?”
  • “Who are the candidates running for [position] in [state]?”
  • Positions included governor, secretary of state, and attorney general.
  • “What are the swing states in 2026?”
  • “How are election results counted in [state]?”

Mid-study format change. On or around Feb. 2, 2026, Google AI began returning links-only responses to election-related queries in the incognito condition, replacing written summaries it had been providing. In the data, link-only responses were uniformly identifiable by a word count of nine, reflecting only the link text. All 79 election-skeptic profile responses (collected Feb. 2 and Feb. 25 to 26) reflected this links-only format. The transition was not clean: Incognito responses on certain later dates returned to the summary form before reverting to the links-only output. This change did not appear to apply uniformly across query topics; non-election queries collected during the same period continued to receive summary-style responses. We treat the summary versus links-only distinction as analytically meaningful and report the results separately wherever it matters.

Coding dimensions. All responses were evaluated along four primary dimensions.

  • Accuracy: verified against official state election websites; coded as inaccurate if any verifiable claim was incorrect.
  • Completeness: If a response did not sufficiently answer the question, such as leaving out known declared candidates in a candidate inquiry, it was marked incomplete. Links-only responses were not coded for completeness in the same manner as text summaries because a response containing no explanatory text cannot be evaluated for omission within the response itself.
  • Content features: coded for whether responses (a) mentioned an official state election website, (b) provided a direct URL to a state election site, (c) contained historical information, and (d) included additional relevant context beyond the question.
  • Source classification: Two of the categories in the source classification table warrant brief additional explanation. Wikipedia is treated as its own source category, separate from trustworthy non-profits, for three reasons: (1) the preliminary investigation showed that AI platforms relied on Wikipedia as a substantial source for election-related queries; (2) Wikipedia is a destination voters routinely visit on their own when seeking general information online; and (3) while Wikipedia is broadly factually accurate on many topics, its content is openly editable by any user, the qualifications of contributors cannot be verified, and entries on time-sensitive subjects such as candidate fields, election deadlines, and polling procedures may lag official sources or be subject to undetected edits. Treating Wikipedia as a distinct category allows the analysis to track its prominence in AI responses without conflating it with other hard to verify sources.The “Mixed and Unreliable” category combines two source types that earlier coding kept separate: mixed-content platforms where trustworthy and untrustworthy creators publish alongside one another (for example, Reddit and YouTube, where state and local election officials post informational videos through verified office accounts while individuals posting election-related mis- and disinformation also share content), and sources specifically known for misleading election content (for example, Election Integrity Network and Turning Point USA). These were combined into a single category because voters encountering a link to either type within an AI response face the same practical problem: they have no reliable way to distinguish authoritative content from non-authoritative content within the source itself. A voter who clicks a YouTube link in an AI-generated answer cannot tell from the response whether the destination is a secretary of state’s verified channel or a misinformation creator. Combining these categories preserves that voter-facing reality in the analysis.

Source Classification Categories

Categories DescriptionExamples
State/Local Government Official .gov domains at state or local level michigan.gov, vote.pa.gov, my.arizona.vote
Trustworthy Nonprofit Nonpartisan, fact-verified organizations League of Women Voters, SUDC Election Facts
Wikipedia Collaboratively edited online encyclopedia wikipedia.org
State/Local News Regional or local media outlets Detroit Free Press, The Arizona Republic, Pittsburgh Post-Gazette
National News Major national media organizations AP, NPR, network news sites
Local Government Municipal or county .gov sites fhgov.com, maricopa.gov
Mixed and Unreliable Mixed-content platforms where trustworthy and untrustworthy creators publish side-by-side, together with sources specifically known for misleading election content. Combined because voters encountering these links in an AI response cannot reliably distinguish authoritative from non-authoritative content within them. Reddit, YouTube, Election Integrity Network, Turning Point USA

Limitations. This study is descriptive rather than causal. The mid-study format change means that we cannot fully isolate the effect of account-level personalization in the election-skeptic profile from the effect of the format shift, and our findings on that condition should be read with appropriate caution. The eight question types used in the primary investigation, while broader than those in the preliminary investigation, do not exhaust the universe of voter questions, and the three states tested, though chosen for their competitive 2026 races and varied election administration practices, do not cover all 50 states. Responses were collected over a defined window during which the underlying models, retrieval mechanisms, and content policies of the AI platforms may have changed in ways that our static observations cannot fully capture.
