What the forecast is built on

On its 2026 lines the district's 2024 presidential lean is D+11.6 relative to the nation. The House model starts from that lean, adds the national environment as a uniform swing, and weighs incumbency (Pete Aguilar holds the seat) and fundraising in the win probability.

  • No public district poll, so the margin is the model's.
  • The rating shops: the win probability also weighs Cook, Inside Elections and Sabato's current ratings; the margin does not.
  • The published forecast: Aguilar +16.8, a 99% chance for Aguilar.
