The 2024 Senate elections are fast approaching. These are the seats up for reelection.
Corrections & Clarifications: The story has been updated to correct David Trone's time of service as a member of the U.S. House of Representatives.
The 2024 presidential campaign is already well underway, but ballots across the country are long, and commander in chief isn't the only position in play.
There are 33 United States senators up for reelection in 2024. Ten are Republicans, three are Independents, and 20 are Democrats.
The upper chamber, which is now controlled narrowly by Democrats, could flip red if the GOP performs well in November. The map is considered to favor Republicans slightly this election cycle, though electoral predictions will continue to evolve, and surprises on the campaign trail are always possible.
Come decision day 2024, these are the states that will see contests for senator, and who currently represents them.
Which senators are up for reelection in 2024?
Arizona
Kyrsten Sinema
Party: Independent
Sinema, once a Democrat, is known for her eccentric fashion choices and her centrist views, which have regularly held up the Democratic policy agenda. Sinema left the Democratic Party in December 2022 over concerns of "rigid partisanship."
Sinema will not run for reelection, citing increased polarization in the Senate. Rep. Ruben Gallego, D.-Ariz., is the leading Democratic candidate to fill Sinema's seat. Kari Lake, a former news anchor and 2022 gubernatorial candidate, is the leading Republican choice.
California
Dianne Feinstein
Party: Democratic
After winning California's "jungle primary," Democratic Rep. Adam Schiff and Republican former baseball star Steve Garvey will be on the ballot in November to fill the seat of the late Feinstein, who died in September 2023. The Super Tuesday ballot featured Schiff, Garvey and two other Democratic House lawmakers: Reps. Barbara Lee and Katie Porter.
Some feel Schiff is to thank in part for Garvey's second-place finish – he spent millions of dollars on ads boosting Garvey in the lead-up to the primary. The race for the liberal state's Senate seat is all but secured for Schiff as Californians haven't voted in a Republican Senator since 1988.
Connecticut
Chris Murphy
Party: Democratic
Murphy has served as the senator from Connecticut since 2013 and is expected to cruise to reelection in 2024 in predominantly blue Connecticut. During his time in the chamber, he has made gun control a major issue, often referencing the 2012 Sandy Hook school shooting in his home state.

Joining her in the primary is Marquita Bradshaw, an activist for environmental justice who mounted an unsuccessful bid for Senate in 2020.
Texas
Ted Cruz
Party: Republican
Cruz, a political firebrand for his party and a two-time presidential candidate, successfully battled off a challenge from Democratic candidate Beto O'Rourke in 2018. For 2024, he may have to do the same. Democratic Rep. Collin Allred, a former NFL player, won the recent Senate primary and will face Cruz in November.
Utah
Mitt Romney
Party: Republican
One-time presidential nominee for the GOP, Romney has come to occupy a minority in recent years, treading a more centrist, anti-Trump line. He has held his Senate seat since 2019, but is not running for reelection in 2024. Many hopefuls are vying for his seat, notably Rep. John Curtis and Brent Orrin Hatch, the son of the late Orrin G. Hatch, a former Utah senator.

Virginia
Tim Kaine
Party: Democratic
Kaine, the vice presidential candidate on Hillary Clinton's ticket in 2016, has represented Virginia in the Senate since 2013. For Democrats who face a tough electoral map in 2024, his race is a must-win. Though Kaine is a veteran of Virginia politics, and the state tends to lean blue, Republican Gov. Glenn Youngkin's win in 2021 proved a red tilt is not far off.
Republican hopefuls include veterans Eddie Garcia and Hung Cao and former Ron DeSantis advisor Scott Parkinson.
