Again, I worked the polls and it doesn't matter whether someone comes in in person or submits an absentee or vote-by-mail ballot. All that shit gets counted by the same people, all of whom have to check the ballots against the voter registration list. The majority of your security concerns should be aimed squarely at the easily hacked voting machines that are used to tabulate all ballots including the paper ballots in most areas. If you had any remaining concern, well that would lie with people who are verifying the count who are largely state government employees. Regular people aren't out there stuffing ballot boxes and if they were they would be election officials who would have no incentive to use mail-in ballots to do that - it would actually take a lot longer to mail out ballots to random voters than to just manufacture fake ballots or, again, hack the very easy to hack voting machines. This is all a fake problem that you've bought into because "Trupm" said so. In fact he's either just talking out his ass or he wants an excuse to declare the election invalid and rule as a dictator.
