What the forecast is built on
On its 2026 lines the district's 2024 presidential lean is R+16.5 relative to the nation. The House model starts from that lean, adds the national environment as a uniform swing, and weighs incumbency (Lauren Boebert holds the seat) and fundraising in the win probability.
- District polls: 1 poll averaging Boebert +5.0, blended with the model by how much each is worth.
- The published forecast: Boebert +9.9, a 95% chance for Boebert.
