The 2006 United States Senate election in Ohio was held November 7, 2006. Incumbent Republican Mike DeWine ran for re-election, but was defeated by Democratic congressman Sherrod Brown.[1] As of 2025, this is the most recent time a Democratic Senate candidate in Ohio won a race by double digits. This was also the last time an incumbent Senator lost reelection in Ohio until Brown was defeated in 2024 by Bernie Moreno.
To date, this is Mike DeWine's second general election loss of his political career, following his 1992 loss to John Glenn. Following his defeat, DeWine would later serve as Ohio's State Attorney General from 2011 to 2019 and has been the state's governor since 2019.
