The sum of every district on the ballot. Each district's turnout is its 2024 top of ticket vote on today's lines, scaled to the forecast's 2026 statewide vote less a small share who skip legislative races, split by the district forecast. A district with no candidate from one party gives all its votes to the other. The district table lists each seat's projected votes.

How this is built
Each district starts from its 2024 presidential vote, read off the precincts that voted in it, and moves with the state's 2026 House forecast and the national generic ballot. Half of what the last legislative winner ran ahead of the district carries over, 2026 primary turnout moves districts where it is posted, and district and statewide legislative polls count by recency and sample. A seat with no candidate from one party is called for the other. 2,000 simulations share a national, a state and a district shock. The map's district shapes are estimated from where each district's voters are in the precinct returns. All chambers.
