AI midterms tracker · United States
Does AI give voters the right facts about the 2026 midterms?
Every day we ask ChatGPT, Gemini and Claude the same questions a voter would ask about registering, ID, mail ballots, early voting and the races in their state, with web search on. Each answer is checked against the state's official rules. The map shows where the answers hold up and where they do not.

This is not a poll and not a voter guide. It measures what AI assistants say, not what is true; the official rules are linked for every state. How we measure

02Where AI gets it wrong
A wrong deadline sends a voter to a closed office. This chapter lists every answer that contradicted the official rule, with what was claimed and what is true.

Race questions are scored on whether the answer names the candidates actually on the ballot and nobody else. Who it calls the favorite is reported in chapter 03, not scored.

03The races
Asked who is running and who is favored, an assistant can name the ballot, pick a winner, or hedge. We record all three and never score the pick: the tracker has no view on who should win.
How the engines frame the contests
| Engine | Answers | Named a favorite | Called it close | Favorite D / R | Ballot recall |
|---|---|---|---|---|---|
| ChatGPT | 9 | 78% | 100% | 6 / 1 | 49% |
| Gemini | 9 | 89% | 78% | 6 / 2 | 72% |
| Claude | 9 | 89% | 67% | 7 / 1 | 65% |
Ballot recall is the share of candidates on the ballot the answer named. "Favorite D / R" counts answers whose named favorite is a Democrat or a Republican; it says nothing about whether the call is right.
Where the engines disagree on the favorite
- TexasChatGPT: James Talarico (D)Gemini: Ken Paxton (R)Claude: too close to call
04Sources
An answer that cites the state election office tends to be right. One that cites a news story about last election tends to be outdated. Where each engine gets its facts.

How an answer is scored
- Correct
- The claim matches the official rule: the same date, the same ID class (photo, non-photo, none), the same registration rule, or the official site.
- Wrong
- The claim contradicts the rule. A different date, a different ID class, a candidate who is not on the ballot.
- Outdated
- The claimed date has already passed, so it is a previous election's date rather than an invention.
- No answer
- The answer gives no checkable claim for the field, for example tells the voter to look it up without saying where.
- Declined
- The engine declines to answer.
Answers are read by one fixed model that extracts the claims into fields; the comparison with the fact table is plain code. Reasons are published for every verdict so a reader can dispute one.
The fact table
For each of the fifty states and DC we keep the registration deadline, same-day registration rule, voter ID class, mail-ballot rule and request deadline, early-voting window, official election site and the certified Senate and governor candidates. Every field is taken from the state election office, with NCSL and Ballotpedia as cross-checks, and carries the date it was last verified. Where a state has several deadlines (online, by mail, in person) each counts as correct.
Fourteen states are measured daily: Arizona, Colorado, Florida, Georgia, Maine, Michigan, Minnesota, Nevada, North Carolina, Ohio, Pennsylvania, Texas, Utah and Wisconsin. Every state is measured on Sundays. Engines are asked with web search on and no system prompt beyond the voter's framing, in English, from a US location.
Models: ChatGPT (gpt-5-mini-2025-08-07 (DataForSEO)), Gemini (gemini-2.5-flash), Claude (claude-sonnet-4-6).
