Mail in ballots in most states if not all couldn’t even begin to be counted until polls closed. Democrats like myself voted heavily that way due to Covid. It’s no surprise that Biden won. Trump had previously lost the popular vote to Hillary and that was with the FBI re-opening the case for her emails right before that election. Your proof is all accusations that wouldn’t pass muster in a court of law. Trump’s plan was to use republican controlled state legislatures to decide to keep their loser in power despite any laws to the contrary. The toady he wasn’t able to get in place at the DOJ planned on using our own military on all the cities to try to quell any unrest.
