Margin from the district's presidential lean on its 2026 lines, one fitted intercept and the national environment as a uniform swing; the win probability adds a decaying incumbency premium (Democratic incumbent running). The 3 district polls are blended in by inverse variance, about 54% of the weight: the model alone said R+0.6.

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).

These polls move the forecast: their average is blended into the model's own margin by inverse variance, with about 54% 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.
