Did anyone check who won? 46 of 51 jurisdictions ran a tabulation audit of some kind, but there are significant differences in audit quality Post-election tabulation audits of the 5 November 2024 General Election, 50 states and DC, by audit method. Split tiles: two programs using different methods. People read the paper ballots Risk-limiting audit (RLA) (11 programs in 9 states) hand-checks enough ballots to confirm the winner of its target races Tiered hand count (3) fixed sample that grows when a race is close Fixed-rate hand count (33) a set share of precincts, scanners or batches A scanner or computer re-counts Full computer re-count (2) every ballot image re-counted by separate software Sample scanner re-count (6) a share of ballots re-run through a scanner Other Records review (1) procedures and paperwork checked; no votes counted No audit in 2024 (4) Could the audit change the outcome? Square: yes, or not known Hexagon: no. Report only or no legal effect, or the audit ran after certification AK ME WI VT NH WA1 WA2 ID MT ND MN IL MI1 MI2 NY MA OR NV WY SD IA IN OH PA NJ CT RI CA UT CO NE MO KY WV VA MD1 MD2 DE AZ NM KS AR TN NC SC1 SC2 DC OK LA MS AL GA HI TX FL1 FL2 What the risk-limiting audits checked CO President and CU Regent, plus one county race in each county GA President IN Voluntary: 7 of 92 counties MI1 President NV One statewide race, plus one county race in each county PA State Treasurer RI President; one State House district VA U.S. Senate; one U.S. House district WA2 Lieutenant Governor Every other race on these ballots was outside the audit’s guarantee. Other methods can find errors, but give no stated chance of catching one large enough to change a result. A full computer re-count checks every race, but reads the same scanned images, so it cannot catch a bad scan or a misread mark. AZ, DE, RI and VA each ran two programs of the same method, shown as one tile. Select any state for details. Rules as in force for the 5 November 2024 General Election.
