Two things bother me There might have been more votes for President than registered voters in the U.S. or damn close.  About 154 Million votes and in 2018 there were 153 Million registered voters.  Then subtract out Judicial Watch's 3.5M people that should not be registered and add Trump's voter registration effort (5-10M guess).  And you have near 100% registered voting in the U.S.  All states would have to be at that rate.  Not possible.  I could not get a good number for 2020 registered voters.   Second item:  In these contested states, I would bet that some have more returned ballots than requested.  Normally it is at about 87% return rate.  Not a lot of wiggle room to create the massive number of votes that they did.
