ATLANTA (AP) — A review by The Associated Press in the six battleground states disputed by former President Donald Trump has found fewer than 475 cases of potential voter fraud, 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 Biden’s victory margin in those states.

Trump, a Republican, has continued to insist that the election was fraudulent by citing a wide range of complaints. The AP review also showed no collusion intended to rig the voting.
