Elections in Ohio |
---|
The 2018 United States Senate election in Ohio took place on November 6, 2018. The candidate filing deadline was February 7, 2018; the primary election was held on May 8, 2018.[1] Incumbent Senator Sherrod Brown—the only remaining elected Democratic statewide officeholder in Ohio at the time of the election—won his reelection bid for a third term, defeating Republican U.S. Representative Jim Renacci by a 6.84% margin in the general election, larger than the 6% margin in the election six years earlier.[2][3] This was one of ten Democratic-held Senate seats up for election in a state won by Donald Trump in the 2016 presidential election. Renacci conceded defeat on November 7, 2018.
With Republican Mike DeWine winning the governorship in the same year, this was the first election since 1974 in which Ohio simultaneously voted for a gubernatorial nominee and a U.S. Senate nominee of opposite parties. As of 2025, this is the last time the Democratic Party won a statewide race in Ohio.
