U.S. House Control and Ohio

Control of the U.S. House may turn on a small number of competitive districts — and Ohio's map, redrawn for 2026, is part of that national battlefield.

Ohio's battlegrounds

• Ohio's 1st Congressional District (2026) — Greg Landsman's seat, redrawn Republican.
• Ohio's 9th Congressional District (2026) — the Marcy Kaptur–Derek Merrin rematch.
• Both shifts trace to Ohio 2025 Congressional Redistricting, which gave the GOP an edge in 12 of 15 districts.

Why it matters

When maps decide seats before campaigns begin, House control becomes partly a Gerrymandering story. See Redistricting (Ohio) and Ohio 2026 Elections.
