Party Control: Upper Body of State Legislature

After the 2020 Census, redistricting will occur, with congressional districts redrawn for the 2022 through 2030 elections. In many states, this process is controlled by the state legislature, subject to gubernatorial veto. When one party controls the process, this can lead to gerrymandering, where district lines are set to maximize that party’s control in Congress.

This three-part map lets you see the current party in control of the Senate in each state. You can also make a forecast for each of the 47 states holding an election in 2019 or 2020. Use the 2021 map to see party control based on your forecast.
