The 2018 Ohio gubernatorial election took place on November 6, 2018, to elect the next governor of Ohio, concurrently with the election of Ohio's Class I U.S. Senate seat, as well as other elections to the United States Senate in other states, elections to the United States House of Representatives, and various Ohio and local elections. Incumbent Republican governor John Kasich was term-limited and could not seek re-election for a third consecutive term.
Republicans nominated Ohio Attorney General and former U.S. senator Mike DeWine, while Democrats nominated former Consumer Financial Protection Bureau Director and former Ohio attorney general Richard Cordray. This was the second contest between DeWine and Cordray, following the 2010 attorney general election, which DeWine won, 47.5% to 46.3%.
In 2018, DeWine defeated Cordray 50.4% to 46.7%, in what was considered a minor upset. Despite Cordray's loss, he became the first Democratic gubernatorial candidate to win Cincinnati's Hamilton County since Dick Celeste in 1982. Likewise, DeWine became the first Republican to win in the historically Democratic Monroe County in a gubernatorial election since 2002 as the county took a sharp turn to the right. With Democratic senator Sherrod Brown winning re-election 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.
DeWine and Husted took office on January 14, 2019.
