Who is forecasted today to win the Florida 13th District House race?

Anna Paulina Luna is favored. The VotePredictor forecast gives Luna a 84% chance of beating Leela Gray, with a predicted margin of Luna +5.3. That is a Lean R race: Luna wins about four times in five, and Gray in the other 16%.

What the forecast is built on

On its 2026 lines the district's 2024 presidential lean is R+12.0 relative to the nation. The House model starts from that lean, adds the national environment as a uniform swing, and weighs incumbency (Anna Paulina Luna holds the seat) and fundraising in the win probability.

• District polls: 3 polls averaging Luna +2.0, blended with the model by how much each is worth.
• The published forecast: Luna +5.3, a 84% chance for Luna.

Misses of a few points are common, so a 5.3-point lead is a 84% chance and not a lock.
