A recent tweet argues that PA rejected absentees at only a 0.03% rate this year, compared to 1% in 2016.
Let’s suppose PA rejected another 0.97% of absentees then. PA has counted 2,615,512 absentee ballots. Even if 100% of these absentees had been cast for Biden, which of course they were not, that comes to about 25,370 ballots.
Biden’s lead, which grows by the day, is currently more than 68,000 votes.
