Campaign money: FEC, through Oct 14, 2026. Outside spending: independent expenditures by super PACs, parties and other groups, primary and general, as reported to the FEC through Nov 1, 2026, updated Nov 3, 2026. It leaves out spending not reported as independent expenditures (most issue ads and much dark money), so it understates all outside money.
