| "Who's winning the Ohio Senate race?" — takes a state name, code, or district ( |
| "Who's favoured to control the Senate?" — control probability, expected seats, biggest movers |
| "Whose election forecast should I trust?" — difficulty-adjusted scores for every major forecaster |
| A member of Congress: ideology, reported net worth, and the race for their seat |
Tools take what a person actually says, not ids you have to look up first.

Nothing is certain. p_dem_win is clamped to 0.01–0.99. An election that hasn't
happened is never 0% or 100%, however safe the seat.
Provenance is always stated. source is polls or fundamentals. Nobody surveys
Wyoming, so its forecast comes from state lean, incumbency and the national environment
instead. Polls take precedence wherever they exist — measured against the seats holding
both, the fundamentals model agrees with the poll-driven one on 15 of 16 safe races but
only 3 of 7 competitive ones.
Some races publish nothing. Where a candidate has left the ballot, the endpoint returns
forecast: null with a reason rather than a number, because the stored probability
describes a matchup that no longer exists. A race we hold nothing for returns 404 — a
different answer, deliberately.
Every forecast is frozen when its race resolves, so the track record can't be edited after the fact. The ratings board scores every model, market, forecaster and pollster on resolved races since 1998, adjusted for how hard each race was — including VotePredictor's own model, ranked in place alongside FiveThirtyEight, Cook and Sabato's Crystal Ball.
Free to use. Please attribute "VotePredictor" and link the specific page. Probabilities change daily until a race is decided.
