How this estimate is made

Every general-election poll goes into one weighted average: newer, larger and likely-voter polls count for more, and no single pollster can flood it. House district estimates use polls alone, so they carry more uncertainty than statewide races. A win estimate is a probability, not a call: a candidate with a 70 percent chance loses three times in ten. Full method and sources.
