THEIR SEAT WAS REDRAWND+6.3 → R+2.6
Ohio had to redraw its map before 2026. The bipartisan Ohio Redistricting Commission voted unanimously for a new plan on Oct. 31, 2025, and it stays in place until the next census. It adds Clinton County and changes which part of Hamilton County it includes. The new lines flip the district, going from Harris +6.3 to Trump +2.6 in the 2024 presidential vote.
