What do the polls say?

14 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. Exact matchups and voter populations stay separate. Percentages describe reported support, not a chance of winning.

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.
