Countdown to 2024: These candidates have already announced Senate plans for next election

The countdown to the 2024 election is on with candidates beginning to announce their intentions to run for Senate seats – or give them up.

Democrats currently have a narrow majority in the upper chamber, but that will be tested next year. Thirty-four seats in the Senate will be up for grabs in the upcoming election, with Democrats (including independents who caucus with Democrats) currently occupying a majority – 23 – of those seats.

The majority party will seek to defend their incumbents in key races again Republican rivals as they look to maintain their slim majority in a presidential election year where President Joe Biden will likely be seeking his second term.

Some members of the House are throwing their names on the ballot for a seat in the upper chamber, while a handful of senators have launched campaigns for reelection. Others have announced they would not be seeking another term, like California Democratic Sen. Dianne Feinstein, the longest serving senator in the state, who announced in February she will be retiring.

Michigan Democratic Sen. Debbie Stabenow has also said she would not be running in 2024. The third-ranking Democrat's departure leaves the GOP with a pickup opportunity in a swing state.

  • Michigan Democratic Rep. Elissa Slotkin. Slotkin will be running for the Senate seat being vacated by current Democratic Sen.
