Hi, I’m Daniel Botkin.

Each average uses the most recent poll from every pollster over the last 30 days, counting each poll equally. Polls sponsored by a party or campaign are left out, and undecided voters aren’t reassigned, so the two numbers usually add up to less than 100. A race with one poll is noisy, so check the poll count. Many House districts have no public polls, so this list can include fewer than 10. Polls are not forecasts.
