Introducing the 2024 Senate Interactive Map

The 2024 Senate Interactive Map is now live. There are 34 seats up in 2024 - including a special election in Nebraska - of which 23 are held by Democrats or independents currently associated with the party.

Democrats hold the majority, controlling 51 of 100 seats as the 118th Congress gets underway. For Republicans to retake control in 2025, they will need a net gain of two seats or one seat along with a victory in the 2024 presidential election.

Independents: The Senate's three independents are up for election in 2024. Along with the usual major party options, the 2024 map allows you to choose an independent in Arizona, Maine, and Vermont. A set of purple gradients is used. Separately, you can elect how to count each independent for purposes of determining the party in control.

Vice President: The VP box is interactive for 2024. Set it as blue or red based on which party you think will win the 2024 presidential election. As the vice president can break ties, that individual's party will have majority control of an evenly split (50-50) Senate. This was the case in the recently completed 117th Congress.
