Republican incumbent Mike Carey maintains a strong position in Ohio’s 15th congressional district, a suburban Columbus area rated R+5 on the Cook Partisan Voting Index. He secured his party’s nomination unopposed in the May primary and holds a significant fundraising edge over Democratic nominee Don Leonard, who narrowly won his primary. Recent polling from Hart Research in August showed Carey leading Leonard by four points among likely voters, consistent with nonpartisan ratings classifying the seat as Likely or Solid Republican. The general election is scheduled for November 3, with no major late-cycle developments reported that have altered the competitive landscape.
