All eligible polls in one complete HTML table, available without scripts. Filters require JavaScript; use the complete table if they cannot load.

Polls by 55 firms are not used and not listed here: firms that fabricated data, campaigns' own polling operations, and firms with no published poll of an election already decided, so no record to judge them by yet. The firms and why.

Polling averages by race

Simple average: the plain mean margin of the race's polls in the 30 days before its newest one, between the two candidates the forecast is between (the Democrat and the Republican in most races; where an independent is the main challenger, the independent). Adjusted average: the nowcast's estimate of the race today -- polls weighted by recency and size, corrected for each pollster's measured lean. Where they differ, the difference is the adjustment. House district polls listed here are inputs to the House model's election-day forecast (each district's estimate is moved toward its own polls, corrected for the sponsor's measured lean); there is no House nowcast. A race the model withholds shows its polls and no adjusted average.
