Late polling in Ohio's 15th congressional district reflects a toss-up between incumbent Republican Mike Carey and Democratic challenger Don Leonard, with surveys from September and October showing margins under 3 points or slight leads for either side. The district's partisan balance after mid-decade redistricting, combined with turnout patterns in Franklin County suburbs and independent voter movement, keeps implied probabilities clustered around narrow outcomes. Recent campaign spending and get-out-the-vote efforts by both parties have sustained the tight positioning ahead of final vote tabulation. Shifts in early or absentee ballot composition, or stronger performance in rural versus suburban precincts, could separate the candidates beyond the current 3-6 point range.
