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.

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. Election.org normalizes dates, matches races, and visualizes reported results; it does not estimate outcomes. Original survey links are attached to each report.

Generic-ballot surveys ask about party preference nationally. They are not polls of any individual district or candidate.

PREDICTION MARKETS · NOT POLLS

What are markets pricing in?

Polymarket widgets

These percentages reflect trading in event contracts—not the share of voters supporting a candidate or an Election.org forecast.

2026 House control

Source, contract rules & market status

These contracts concern national chamber control, not an individual race. Separate contract prices need not add to 100%. A “No” price is not automatically the opposing party’s price.

Prices are supplied and updated directly by Polymarket. If a widget is blocked or unavailable, use its source link; Election.org does not substitute a cached price or zero. Trading buttons are disabled. Widgets contact Polymarket when loaded; privacy details.

How to read these polls and what’s covered

House and Senate race pages come from the existing 2026 FEC filing directory, not certified ballot lists. Governor pages cover states with surveys in the connected feed. No poll is evidence that a person has qualified for the ballot.

Recent means fieldwork ended in the last 30 days. Polls are sorted by fieldwork end, not import date or candidate performance. Matchups and surveyed populations are kept separate. Support percentages are quoted as supplied, not adjusted or averaged.

VoteHub’s API does not currently include collection mode or reported margin of error. Those fields say “Not supplied in this feed,” with a link to the original report. We do not derive uncertainty from sample size alone. See AAPOR’s disclosure guidance ↗.

A scheduled job checks the structured VoteHub API hourly, validates each feed, and saves the last good data independently of page visits. Failed or unexpectedly truncated feeds do not replace those records. Coverage is not exhaustive; missing polls never mean zero support. Check feed health →
