Democrats had 14 seats up for election while Republicans had 21. In order to maintain their majority in the Senate, Democrats had to defend Catherine Cortez Masto in Nevada, Raphael Warnock in Georgia, Mark Kelly in Arizona, and Maggie Hassan in New Hampshire, all of which represented states that incumbent President Biden had won in 2020. Republicans had also targeted senators in traditionally Democratic states such as Michael Bennet of Colorado and Patty Murray of Washington, while Democrats attempted to pick up open seats in Pennsylvania, North Carolina, and Ohio. Pennsylvania was seen as the most likely flip for the Democrats, while Nevada was seen as the most likely flip for the Republicans. Democrats had overperformed in the 2022 elections overall, with incumbents Maggie Hassan and Mark Kelly winning by larger margins than anticipated, and Democratic challenger Mandela Barnes losing to Wisconsin senator Ron Johnson by a much smaller margin than expected. Democrats flipped the open seat in Pennsylvania, electing Democrat John Fetterman over Republican Mehmet Oz to replace Republican Pat Toomey. Upon Catherine Cortez Masto's narrow victory over Adam Laxalt in Nevada, it was projected that Democrats would retain 50 senators and thus maintain control of the U.S. Senate. A runoff election between incumbent Democrat Raphael Warnock and Republican challenger Herschel Walker ultimately ended in Warnock prevailing, leaving Democrats with a 51-49 majority after the elections. 2023-2024 election cycle Senator Gary Peters of Michigan was selected as DSCC chair for a second consecutive cycle, the first since Chuck Schumer to do so.
