2024 United States Senate election in Ohio

The 2024 United States Senate election in Ohio will be held on November 5, 2024, to elect a member of the United States Senate to represent the state of Ohio. Primary elections took place on March 19, 2024. Incumbent Democrat Sherrod Brown is seeking a fourth term in office, while the Republican Party nominated former car dealer Bernie Moreno. This race is one of two 2024 U.S. Senate races in which Democratic senators are seeking re-election in states where Republican Donald Trump won both the 2016 and 2020 presidential elections. Brown's re-election is considered essential for Democrats' chances to retain the Senate majority in 2024. The last time Republicans won this seat was in 2000.

Background
Ohio has trended towards Republicans in recent years and is now seen as a moderately red state at the federal level. Republicans hold the other U.S. Senate seat and all statewide executive offices along with majorities in both state legislative chambers and the U.S. representative delegation. However, in the 2022 midterms Democrats managed to net a gain of one seat in Ohio's U.S. House delegation.

Former President Donald Trump won Ohio in both the 2016 and 2020 presidential elections by slightly over 8 points. Republican J. D. Vance, now the 2024 Republican vice presidential nominee, defeated Democrat Tim Ryan in the 2022 U.S. Senate election by slightly over 6 points.

Brown was first elected in 2006, defeating then-incumbent U.S. Senator Mike DeWine (now governor), and has won reelection in 2012 and 2018. Despite Ohio becoming a reliably Republican state in recent years, Brown has remained popular among his constituents. Because of this, the race is considered to be a tossup; however, most polls show Brown to be the favorite to win.
