Democrats hold a strong trader consensus around winning exactly three of Iowa’s four U.S. House seats following the November 3, 2026 election. Pre-election forecasts and final polling averages positioned three districts as competitive or leaning Democratic after shifts in the Cook Political Report and other models, driven by rematches in IA-1 and IA-3 plus an open IA-2 seat. On election night, Christina Bohannan defeated incumbent Mariannette Miller-Meeks in IA-1, Lindsay James won the open IA-2, and Sarah Trone Garriott defeated Zach Nunn in IA-3, while Republican Chris McGowan held the safely Republican IA-4. These outcomes align with a broader Democratic performance in Iowa’s statewide races and reflect voter turnout patterns plus district-specific margins that have held in updated counts. Late-counting precincts or certification delays represent the primary remaining uncertainty for full resolution.
