How the forecast was built
| Statewide generic legislative margin (environment) | D+2.9 |
| + District partisan lean | +40.9 |
| = Expected party margin (mean Democratic candidate vs mean Republican candidate) | D+43.8 |
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 1 by share win. Independents are placed with the weaker major party minus a 6.0-point penalty.
