The2006 United States Senate election in Ohio was held November 7, 2006. Incumbent RepublicanMike DeWine ran for re-election, but was defeated by Democratic congressmanSherrod 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 in2024 byBernie Moreno.
To date, this isMike 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.
TheincumbentRepublican SenatorR. Michael DeWine had approval ratings at 38%,[2] making him the second most unpopular U.S. Senator behindPennsylvania RepublicanRick Santorum, who was also up for reelection in 2006. Pre-election stories in the U.S. media suggested that the national Republican Party may have given up on saving Senator DeWine's Senate seat before election day.[citation needed]Sherrod Brown, formerOhio Secretary of State and U.S. Representative fromOhio's 13th district, easily won the Democratic nomination overMerrill Keiser Jr.
Both candidates campaigned as conservative alternatives to DeWine, citing DeWine's support for gun control measures and his role as one of the Republican members of theGang of 14 which was a group of Republicans who compromised with Democrats in a dispute about judicial appointments.

The Republican Party, which was facing multiple challenges to their Senate majority, was initially determined to assist DeWine in his competitive race while the National Democratic party supported Brown in hopes of taking control of the Senate. John McClelland, a spokesman for the Ohio Republican Party said, "It's vitally important to the Republican Party as a whole, so I think that's why you see the president coming to Ohio to support Mike DeWine." Phil Singer, a spokesman for the Democratic Senatorial Campaign Committee said, "Mike DeWine Senior is in for the fight of his life, make no mistake about it."[4]
On July 14, 2006, DeWine's campaign began airing TV commercials depicting a smokingWorld Trade Center. "The senator was notified... by a reporter atU.S. News & World Report that the image of the burning Twin Towers could not have depicted the actual event because the smoke was blowing the wrong way."[5][6] DeWine's campaign admitted that the video was actually a still photo of theWorld Trade Center with smoke digitally added.[5] He also was criticized for using an emotionally charged image to attack his challenger.[6]
Another of DeWine's ads suggested that opponent Sherrod Brown didn't pay his taxes for thirteen years. This claim led to the Associated Press reporting on October 19 that, "Several Ohio television stations have stopped airing a Republican ad because state documents contradict the ad's accusation that Democratic U.S. Senate candidate Sherrod Brown didn't pay an unemployment tax bill for 13 years." Brown produced a commercial citing these facts.[7] DeWine's ads were changed to state only that he had failed to pay his unemployment taxes until legal action was taken against him.
On October 16, 2006,The New York Times reported that top national Republicans were moving resources away from the Ohio Senate race, as they had determined that DeWine was likely to lose and were seeking to spend money on races where Republican candidates were seen as having a better chance of winning.[8]
During the election cycle, DeWine raised $14.9 million and spent $15.5 million.[9] Brown raised $8.9 million and spent $10.8 million.[10]

Brown was declared the winner right when the polls closed inOhio at 7:30. DeWine had the second worst performance of a Republican incumbent in 2006; only Pennsylvania SenatorRick Santorum had aworse performance. While DeWine was able to win rural counties in western Ohio, Brown managed to win most eastern Ohio counties, especially in heavily populated areas. DeWine's narrow 2,000 vote victory inHamilton County which is home toCincinnati, came nowhere close to making a dent in Brown's lead. Brown would go on to be reelected to a second term in2012, and a third term in2018. Also in 2018, both Brown and DeWine were on the ballot but this time for different races; DeWine would beelected Governor of Ohio. In 2024, Brown would be defeated for reelection.
