"What is tolerable in small numbers breaks down when you expand it to millions."
Tens of thousands isn't a small number.
And the story would be a simple one: I got a mail-in ballot, and my (roommate/sibling/parent) took it, and voted for Biden.
After a close election, folks would've come out of the woodwork in droves, all telling the same story. Even if 99% of the victims never made a peep, that'd be HUNDREDS of victims coming forward.
Instead, after five years, we've seen ZERO voters make your claim.
Statistics and human nature teach us at least SOME of the tens of thousands would speak up. The fact NO ONE has come forward, 5 years later, and you're still clinging to an impossible scenario, just makes you look clueless.
Or worse: like you're purposely bearing false witness, for a political purpose.
Jesus wept.
Bill, here are people who study this issue, and might be able to explain why your theories have no evidence:
