Mike Turner holds an 84.5% implied probability in the OH-10 House election market due to his long incumbency, consistent reelection margins, and strong fundraising edge over Democratic challenger Kristina Knickerbocker. The district’s newly redrawn boundaries, approved in October 2025, incorporate additional Republican-leaning areas in Butler County while retaining core Montgomery and Greene County strongholds tied to Wright-Patterson Air Force Base. Turner advanced unopposed in the May 2026 Republican primary, while Knickerbocker secured the Democratic nomination after a multi-candidate contest. Recent analyst ratings classify the seat as Likely Republican, reflecting Turner’s local profile and the district’s partisan lean despite national headwinds for the GOP. A Libertarian candidate is also on the November 3 ballot but has minimal impact on the two-party contest.
