Baseline model (incumbency Γ— party Γ— office). Calibration: backtest Brier score is the reference, see npm run db:ingest -- --source=predict-backtest-election. Future model versions must beat baseline Brier on the same held-out cohort or they don't ship.

Every candidate, committee, bill, vote, member, and nonprofit on this site is mirrored from primary U.S. government sources (FEC, congress.gov, govinfo.gov, IRS) and each state's Secretary of State / election commission β€” no third-party data vendors, no paywall, no editorial intermediation. Citations to the originating source are on every detail page.
