POLLING · SURVEYS, NOT PREDICTIONS

What do the polls say?

30 survey records

Reported support, with field dates and original sources. Surveys cover 2026 contests, including earlier cycle history from 2025. Older or hypothetical matchups do not establish who is on the current ballot.

Included surveys & calculation

Add each answer’s reported support across these 5 surveys and divide by 5. No house effects, sample weights, undecided allocation or error band is applied. Figures are not rescaled to total 100%.

How the average works

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. Incomplete numeric matchups are excluded from this calculation but remain in the survey history. Full methodology →

Dots show reported support; connecting lines are not an average or forecast.

How to read this chart

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.

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.

FILING RECORDS

Not the certified ballot.

Seat identity and the election schedule are verified separately from FEC filings. A filing does not establish ballot qualification.

How to use this race page

November candidate names come from the official general-election sources linked beside each person. Registered write-ins have their own list. FEC filing history preserves earlier primary and other campaign records; filing or fundraising alone does not establish November eligibility. Confirm your full local sample ballot with the election authority.
