Election Auditing in the US
After the 5 November 2024 General Election, most states checked their vote counts against the paper ballots. This site compares how each of the 50 states and DC did it: what was checked, how much, who did the checking, and whether the check could change a result.

Why this website
Why election audits are hard, and what makes one useful.
Did anyone check who won?
A map of the audit method each state used. Only 9 states ran an audit designed to confirm the winner, and each checked only one to three races.
Depth or breadth
Audits built to confirm a winner checked few races. Only 4 checked every race, using ballot images or a sample spread across every county.
What happens when an audit finds a problem?
33 of 56 audits must expand when they find a discrepancy, but 6 of those run only after the results are certified.
What gets audited?
Precincts, batches, machines or single ballots. 41 of 55 audits can reach mail and early ballots; 11 leave some or all of them out.
Each opens a summary with links to the law and the published results, or a note that results are not online.
