Margin: the poll's lead (D − R; approve − disapprove for approval). Forecast: the race's chance in today's forecast, which averages polls after adjusting for each pollster's house effect and track record. Stars: our pollster rating, three is best. Sponsor: polls paid for by a party or campaign are released selectively, and the forecast adjusts for that.
