Trifecta

Democratic trifecta now

Democrats hold the governorship and every legislative chamber. A trifecta is one party holding all of them.

Chances come from the same simulations as the races, so outcomes are correlated. A governorship or chamber not on the ballot this year keeps its current party. Source: 99chambers forecast, run 56, updated Oct 16, 2026.

Statewide races

Every race decided by the whole state.

The New Jersey environment

The environment New Jersey's governor, statewide and legislative races run in, read from their polls against what the fundamentals expect. Its federal races run in the national environment.

The polled state races behind it

No governor, statewide or legislative race in New Jersey is polled yet, so its state races run at the national environment.

Each polled race's average, minus what the fundamentals expect at the national environment, in national-environment points (a dot right of center runs more Democratic than expected). Readings are weighted by poll precision and office (governor most, then other statewide races, the Senate, legislative and House races), centered on the national average and pulled toward zero, so a thinly polled state stays near the nation. Governor, statewide and legislative races use the New Jersey environment in full; Senate and House races 0% of it. Each race's own polls are left out of the environment it uses.

Lean: how much more Democratic (D+) or Republican (R+) the place voted for president than the nation (2024 weighted 75%, 2020 25%). Ratings follow the chance of winning: Toss-up 40–60%, Lean 60–80%, Likely 80–95%, Solid 95%+. INC = incumbent running. D flip / R flip: another party is favored (60% or more) over the party holding the seat now (hover for the chance it changes parties); Flip risk: the seat is a toss-up (40–60%).
