Marcy Kaptur secured reelection in Ohio’s 9th Congressional District on November 3, 2026, with 52.7% of the vote to Republican Derek Merrin’s 47.3%, producing a 5.4-point Democratic margin once 97% of precincts reported. The Associated Press called the race for the incumbent Democrat shortly after midnight on November 4. The rematch occurred on newly redrawn lines that shifted the district toward Republican performance in prior cycles, yet Kaptur maintained strong support in Lucas County while Merrin carried several rural counties. Official certification remains pending, though the current tally aligns directly with the leading market outcome for a Democratic win of 3–6 points.
