Sources and methodology
The map is a scenario builder, not a forecast. The table shows 12 selected districts and the people currently holding those seats; it is not a complete list of 2026 nominees or an official ratings table. House-control odds come from Polymarket. Current membership and vacancies are checked against the House Clerk.
