that happens as a regular occurrence some times triggered by a % of vote difference as stated in the rules of a count.
But then, irregularities in the "hanging Chad" were found and then the destruction of absentee ballots were found and then the Harris miss using State and Federal law on voting practices
and then the subsequent Justices rule of going against law and not recounting ballots.
Rules broken by state officials were blatant.
That is not the same things as saying the vote was rigged - though as it turned out, it was rigged but not the basis of the count.
But you're right, many on the left knew something was amiss - but as it turned out, they were right.
