That’s not it. A lot more mail in ballots, which are more prone to fraud.
As expected since there was, you know, a pandemic. More prone to fraud? Then show me one single example of significant fraud using mail in ballots. Or one shred of evidence of it ever happening. Because we have always had mail in voting. So show me evidence, not conjecture.
Your historically unpopular president got a record amount of votes and 12mil more than the last election.
He did, eh? So, apparently, in your world, all the fraud and overcounting (whatever the fk that distinction means to some people) was for Biden. And you think that sounds sane. Come on. No you don't. Listen to yourself.
He got that many votes because the participation rate shot up. You do know we measure popularity of Presidents in this sense by proportion, not by 'number of 'votes for', right? Historically unpopular. So unpopular, he drummed up an awful lot of votes against himself.
