An Associated Press review of every potential case of voter fraud in the six battleground states disputed by former President Donald Trump has found fewer than 475 — a number that would have made no difference in the 2020 presidential election.

Democrat Joe Biden won Arizona, Georgia, Michigan, Nevada, Pennsylvania and Wisconsin and their 79 Electoral College votes by a combined 311,257 votes out of 25.5 million ballots cast for president. The disputed ballots represent just 0.15% of his victory margin in those states.

The review also showed no collusion intended to rig the voting. Virtually every case was based on an individual acting alone to cast additional ballots.
