The polls behind it

5 polls · newest first

Each pollster name links to the poll's source; the grade under it is its VotePredictor grade from past elections. Margin is the poll as published. The ± under the sample size is the 95% margin of error on each candidate's share, from the sample size (the gap between them is about twice as uncertain). VotePredictor adjusted (“Our adj.” on small screens) is not a poll: it is our correction of that poll, for its pollster's record in past elections and for registered-voter or all-adult samples. It is the number our forecast reads.

The source we collect records each outlet's rating category, not a probability; some of these outlets run models with their own numbers on their sites. The ≈ figure is the standard conversion of the category (Toss-up 50%, Tilt 60%, Lean 75%, Likely 90%, Solid 99%), the one our scorecard grades them on, not a number they published. They remain independent of VotePredictor. Sources and update dates ↗

Independent models

Win probabilities published by independent statistical models, shown with credit as their terms allow: Who Shows Up (whoshowsup.net), by Kurt Wirth. These are their numbers, not ratings converted by us, and not VotePredictor's. The better-known model forecasters (Decision Desk HQ, FiftyPlusOne, Silver Bulletin, the Economist) don't permit republishing their probabilities, so they appear above by rating only.
