How legitimate were those 20,000 provisional and absentee ballots in PA that were finally accepted? How do we know the voter didn’t vote in two different polling places or vote their dead relatives? How many of the provisional ballots were finally rejected as improper and how many were accepted and why were they accepted? I don’t want to wake up one day and see the Dems flipped PA.
That's why it takes almost a month to post the final results. They actually do examine them all.
The typical scenario with a provisional ballot is this: A voter shows up to vote on Election Day in the wrong precinct. There is no record of them among the registered voters in that precinct, so they are permitted to cast a ballot that is set aside and is only counted if it is later verified as a legitimate vote after the election staff confirms that they ARE legally registered in their home precinct.
These cases usually involve newly registered voters, and stupid people who can't even read the instructions that are mailed to them telling them where to vote.
It should come as no surprise to anyone that most people who find themselves in this situation are Democrats, which is why most of these "found" votes in the final tallies end up being added to the Democratic candidates' totals.
