Longtime U.S. Rep. Mike Turner's 24-year career in Congress is coming to an end. Two days after Election Day, the Associated Press and CNN called Ohio's 10th Congressional District for Democrat Kristina Knickerbocker, a political newcomer who unseated one of the House's most senior Republicans in a district long considered safe for his party.

Unofficial results from the Ohio Secretary of State's office show Knickerbocker defeating Turner 49.3% to 47.7%. Libertarian candidate Thomas McMasters received nearly 3%. Decision Desk HQ put the margin at 4,938 votes out of more than 300,000 cast, with Knickerbocker at 149,024 votes and Turner at 144,086. The results remain unofficial until county boards of elections and the Secretary of State complete the canvass and certification.

The 10th District covers Montgomery and Greene counties and part of Butler County, centered on Dayton. It includes Wright-Patterson Air Force Base, the largest single-site employer in Ohio, with 19,000 on-base jobs. The seat had been considered safely Republican, but the Cook Political Report changed its rating to leans Republican in mid-October as the race tightened.

Turner, 66, had won his previous 12 congressional races by comfortable margins — a low of 56% in 2018 and a high of 68% in 2010 — and served two terms as Dayton's mayor before going to Congress. In Washington, he focused on international relations, intelligence and military affairs, and chaired the House Intelligence Committee until House Speaker Mike Johnson removed him from the post in January 2025, ahead of President Donald Trump's return to the White House.

Turner had at times clashed with Trump, publicly criticizing him for repeating false claims that Haitian immigrants in Springfield, Ohio, were eating people's pets. He is also a strong supporter of U.S. aid to Ukraine.

Knickerbocker is a U.S. Air Force veteran who served 10 years of her military career at Wright-Patterson. She is currently an oncology nurse practitioner who lives in Yellow Springs, in Greene County. She declared victory on election night, telling supporters that "we are seeing everyday people stand up against the status quo of Washington because each and every one of us knows we deserve better."

Democrats viewed the 10th District as an opportunity to flip a seat, and the House Majority PAC and the Democratic Congressional Campaign Committee poured money into supporting Knickerbocker. Her win was one of three Republican-held Ohio House seats Democrats flipped on Tuesday, along with Brian Poindexter's defeat of Rep. Max Miller in the 7th District and Don Leonard's upset of Rep. Mike Carey in the 15th. Democrats will hold eight of Ohio's 15 seats in the next House.
