Each state shaded by the partisan lean of its 1980 House delegation — the net of its Democratic and Republican seats. Hover for the split.
Gold marks a state an independent or third-party candidate carried — the blue/red ramp is the Democratic-vs-Republican margin only where a major party won.
Delegation lean is (Democratic − Republican seats) ÷ total seats; an evenly split delegation reads neutral, and a one-seat state shades fully to its winner.
