Incumbent Republican Mike Carey holds a substantial edge in Ohio’s 15th congressional district, where the partisan voting index favors Republicans by five points and forecasters rate the seat Solid Republican or Likely Republican. Carey secured his party’s nomination in the May 2026 primary and benefits from incumbency, established fundraising, and the district’s suburban and rural makeup spanning Columbus outskirts. Democrat Don Leonard won his primary but faces structural headwinds in a contest few models view as competitive. Recent updates from the Cook Political Report reinforce the Republican positioning, with trader consensus reflecting the limited path for an upset absent a major national shift or late-cycle development before the November general election.
