About this election
The electoral system
Thirty-five seats were on the ballot — the Class 2 senators plus special elections in Arizona and Georgia. Georgia's two races were pivotal: under state law a candidate must win an outright majority, and because neither of its seats was decided in November, both advanced to run-offs in January 2021 that ultimately determined control of the Senate. The map on this page reflects the final outcomes, including those Georgia run-offs.
