Part of the Which party will control Congress after the 2026 midterm elections? topic →
Democratic control requires Democrats to win both chambers. Democrats are heavy favorites for the House at approximately 82% probability based on external sentiment and the D+6.9 generic ballot margin. However, the Senate remains a tougher climb, with Republicans holding a 53.5% edge in external markets. The composite probability of ~82% House times ~47% Senate yields roughly 38% for unified Democratic control. Key Senate races in Maine (Platner leading Collins by 7-9 points) and North Carolina provide Democratic upside, but the overall Senate map favors Republicans slightly.
