What counts as a competitive House race?
The table focuses primarily on districts rated Toss-up or Lean Democratic/Republican, while also including selected Likely races that remain politically significant or could become more competitive as Election Day approaches.
Districts rated Solid are not included in the primary table. Selected Likely races may be included when they remain politically significant or could become more competitive before Election Day.
Where the battle for the House is concentrated
Arizona and the West: Open and closely divided districts in Arizona, California, Colorado and Washington provide both parties with realistic opportunities. Several western districts have repeatedly produced close results or were reshaped before the 2026 election.
The industrial Midwest: Iowa, Michigan, Missouri, Ohio and Wisconsin contain numerous districts where recent presidential and congressional results moved in different directions. Missouri will use its 2022 congressional map for the 2026 general election after the U.S. Supreme Court blocked the newer Republican-drawn map on September 25. The operative map preserves the Democratic-leaning Kansas City district and places MO-02 in Cook’s Likely Republican category. These races will be central to either party’s path to 218 seats.
The Northeast: Competitive seats in New Jersey, New York and Pennsylvania include suburban districts, open seats and rematches that attracted substantial national attention in 2024.
The South: Redistricting changed the battlefield in Florida, North Carolina and Texas. Several Democratic incumbents now face more Republican-leaning districts, while Republicans must defend a number of closely divided seats elsewhere.
