I think the issue Trump and the election deniers had is the MASSIVE irregularities in absentee/mail in votes vs those who went to the polls. For example, in Pennsylvania, nearly 3 out of 4 people that went to the polls voted for Trump, then the mail in votes come in and nearly 3 out of 4 Pennsylvanians voted for Biden. This certainly is not an accurate representation of the electorate, regardless of which candidate you support. The same thing happened in nearly every other state, with Biden winning nearly every absentee vote in every state, and Trump winning nearly every in person vote in every state. Then weird shit like Biden winning 60% of the absentee vote in places like South Carolina, a Republican stronghold where Trump smoked Biden at the actual polls. And at the polls you show your face, most states demand I.D. and thus some consider it a more valid form of voting. I voted by mail and there was no verification at all other than me writing that I am who I say I am. And this signature verification for tens of millions of votes is bullshit. Trump won at the polls, Biden won at the mailbox. And that doesn't sit right with many people who want a fair and just election, regardless of who wins. The manner of voting should not influence any election. At least not to this degree.
