Historical Senate Results

Past Senate Maps

Choose an election cycle to see every U.S. Senate race in that cycle. States are filled by the party that won; states without a Senate election that cycle stay gray. If a state held two Senate elections with different-party winners, the state is split between both colors.

Use the election-cycle selector above to compare which party won Senate races across the United States in each selected year. A colored state indicates the winning party; gray states had no Senate election during that cycle. Select or hover over a colored state to view the winning candidate when the results dataset is available.

Senate races operate on staggered six-year terms, so only a portion of states normally elect senators in any single cycle. Special elections can create additional contests. When a state held two Senate elections in the same year, the visualization can show both party outcomes using a divided tile. These historical results describe past elections, not predictions about the next one.

For context beyond the winner, explore how election polling compared with actual results from 2000 through 2024.
