How the forecast was built

Statewide generic legislative margin (environment)D+2.9
+ District partisan lean-17.3
= Expected party margin (mean Democratic candidate vs mean Republican candidate)R+14.4

Each candidate's share is the party's share plus 2.5 points if an incumbent, plus a candidate-specific draw (SD 3.5 points, estimated from how far same-party candidates finished apart in 2022 and 2024). The district margin itself carries statewide, regional and district error (district SD 5.0 pts). The top 4 by share win. Independents are placed with the weaker major party minus a 6.0-point penalty.
