POLLING · SURVEYS, NOT PREDICTIONS
What do the polls say?
20 survey records
Individual surveys of 2026 contests, including earlier cycle history from 2025. Matchups and populations stay separate; older or hypothetical matchups do not establish who is on the current ballot.
Simple average, not a forecast
Each pollster’s latest general-election survey ending within the last 30 days, with equal weight. Reviewed candidate identities join spelling variants; different matchups and voter populations stay separate. Percentages describe reported support, not a chance of winning.
Newest fieldwork appears first. When dates tie, the default favors more pollsters not marked internal or partisan in this 30-day window. Source labels remain visible; this is not a pollster-quality rating.
Likely voters · 6 polls
Sep 22, 2026–Oct 12, 2026 · Lead between the two highest answers: 7.6 percentage points
Add each answer’s reported support across these 6 surveys and divide by 6. No house effects, sample weights, undecided allocation or error band is applied. Incomplete numeric matchups are excluded from this calculation but remain in the survey history. Full methodology →

Party colors: Republican red, Democratic blue, Independent purple. Other or unmatched affiliations are gray. Dash patterns distinguish candidates sharing a color.
Dots show reported support. Lines connect surveys over time—not an average or forecast. Pollsters can differ. Missing values and multiple surveys ending on the same date break the lines.
How to read this chart
No average, trend estimate, or win probability. Different matchups and populations are not combined. Dates mark the last day people were surveyed. The vertical scale always starts at zero; use “Full 0–100% scale” to compare charts on the same scale. The number of people surveyed is the survey sample size, not the number supporting a candidate. Select “Survey source” to inspect every report, including overlapping dots.

Individual reports. Original sources and methodology below.
Labels and figures are supplied by VoteHub. A listed matchup does not establish ballot qualification or primary/general-election status unless the source explicitly says so. Unlisted responses may include undecided voters or other choices; the displayed figures are not rescaled to total 100%.
Polling compilation: VoteHub · CC BY 4.0. Electionpedia normalizes dates, matches races, and visualizes reported results; it does not estimate outcomes. Original survey links are attached to each report.

Follow campaign money
Governor campaigns file with their state’s campaign-finance authorities. Federal candidate totals do not describe this race.
A ballot brings together several decisions that share an election date but may follow different rules. The office, jurisdiction and stage of the election tell you what each choice means.
Start with the office and the place
An election record describes a particular office or question in a particular jurisdiction. A statewide contest is different from a congressional district, a city council seat or a school district. An address can help connect those boundaries, but a ZIP code alone is not a guarantee of one exact ballot. Use the election authority’s own ballot lookup to confirm the final choices for a voter.
Separate a filing from a ballot appearance
A campaign-finance filing tells you that a financial record exists. It does not, by itself, establish that the person qualified for the November ballot. A primary participant, withdrawn candidate and certified general-election candidate can all leave public records. Read the election stage and the source label before treating a directory as a current candidate list. Registered write-in candidates are a separate category whose rules depend on the jurisdiction.
