DAYTON — Democratic newcomer Kristina Knickerbocker is leading longtime Republican U.S. Rep. Mike Turner in Ohio’s 10th Congressional District, putting the Dayton-area seat on the verge of flipping. With nearly all precincts reporting, Knickerbocker held 49.3 percent of the vote to Turner’s 47.7 percent in unofficial results from the Nov. 3 general election reported by the Ohio Secretary of State, according to The Columbus Dispatch.
The Associated Press results page showed Knickerbocker with 149,024 votes to Turner’s 144,086 — a margin of 4,938 votes — while Libertarian Thomas McMasters drew nearly 3 percent. Decision Desk HQ called the race for Knickerbocker early on Nov. 4, according to its published returns, although the Associated Press still listed the contest as too early to call, and The Cincinnati Enquirer described Turner as likely a loss. All results remain unofficial until they are certified.
The 10th District covers Montgomery and Greene counties and part of Butler County, anchored by Dayton and Wright-Patterson Air Force Base. The base is the largest single-site employer in Ohio, with 19,000 on-base jobs, according to The Columbus Dispatch.
Turner, 66, has represented the Dayton area in Congress for 12 terms and previously served two terms as Dayton’s mayor, according to The Columbus Dispatch. He won his previous 12 congressional races comfortably — a low of 56 percent in 2018 and a high of 68 percent in 2010, The Columbus Dispatch reported. A former House Intelligence Committee chairman removed from that post by Speaker Mike Johnson in January 2025, Turner focused on intelligence and military affairs and clashed publicly with President Donald Trump over false claims about Haitian immigrants in Springfield, according to The Columbus Dispatch.
Knickerbocker brings a Wright-Patterson background of her own. She is a U.S. Air Force veteran who served 10 years of her military career at Wright-Pat and now works as an oncology nurse practitioner, and she lives in Yellow Springs, according to The Columbus Dispatch. National Democratic groups treated the seat as a genuine pickup opportunity — the House Majority PAC and the Democratic Congressional Campaign Committee poured money into her campaign, and the Cook Political Report moved the race from safe Republican to leaning Republican in mid-October, according to The Columbus Dispatch.
The county returns show how close the contest was. In Greene County, Turner finished ahead, taking 27,079 votes, or 53.44 percent, to Knickerbocker’s 22,282 votes, or 43.98 percent, with all 151 precincts reporting, according to The Jamestown Comet. Knickerbocker built her lead elsewhere in the district, enough to overcome the incumbent despite his strength in Greene County.
For Miami Valley residents, a change in representation would end more than two decades of continuity in the district’s dealings with Wright-Patterson. County boards of elections will canvass the ballots and results must still be certified before they become final, and both campaigns are expected to watch that process closely given the narrow margin. The winner is set to take the seat when the new Congress convenes in January.
