Races that went to a runoff show the runoff result. Margins are the popular-vote gap as a share of all votes cast in the race.

Results compiled from certified state returns by the MIT Election Data and Science Lab (CC0). Numbers only, no interpretation. Election results and migration data are separate datasets; this site does not connect one to the other.
