And while I'd bet the farm that Trump won the election if you counted only legal votes sending it back to the states in question made no sense to me. The entire issue of the 2020 election, to me, was if a mail in ballot said "John Smith" on it the question is was John Smith the one who actually filled out the ballot? The only way to know that is to match the signatures and that would take months. That's assuming you had all the forensic experts in place already to conduct the audit which they didn't.
There are other issues as many people almost certainly voted more than once. Several on my family received multiple ballots and the rejection rate was near zero so we know they didn't check for fraud. Also, was the voter still alive and legal to vote in the state they voted. But the bottom line is, by January 6 it was far too late.
