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.

These polls move the forecast: their average is blended into the model's own margin by inverse variance, with about 39% of the weight on the polls (a single poll gets about half; more polls, more weight). The rule was preregistered and validated on 321 polled districts from 2018–2024. See methodology.
