How this race is decided

Top-two primary

All candidates run in one primary regardless of party and the two with the most votes advance, so two candidates of the same party can meet in November. The forecast then marks the seat as safe for that party.

Range of outcomes

Final margin across our simulations; the white dashes mark the middle 80%.
