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. Michigan's Senate map was redrawn by court order in Agee v. Benson, approved July 26, 2024, for the 2026 elections. Each district's lean is the 2024 presidential vote on the new lines, and the 16 metro Detroit districts that were redrawn carry no weight from their 2022 results. The map's shapes for the redrawn districts still follow the older lines. All chambers.
