Bars show how many seats turn blue at each step. Dashed lines mark where Democrats reach a majority and a supermajority.
Note: Each district's score, rounded to the nearest whole point, is shifted by the same number of points, and a seat turns blue once the swing matches or beats its lean. An R+2 seat turns blue at D+2. The map starts from who holds each seat today, and Democratic-held seats stay blue at every step. The 2024 figure is the incumbent's own vote share, and 100% means unopposed.
