Maybe. We've never had massive mail in voting like this before, so I don't think it's accurate to say something is impossible.
Here is where the fraud took place.
The Democratic Governors and some politicians wanted to relax the vote scrutiny because of covid. They claimed there would be to many mail in votes to scrutinize and count.
They wanted to relax the allowable time frame for excepting votes and relax the vote verification process.
The Trump campaign challenged this in the SC. The SC threw it back to the State Courts, the State Courts upheld the Governors requests.
The problem with this is it is unconstitutional for the Governors or State Judges to make this decision.
The US constitution clearly states the State Legislature and only the State Legislature can make changes to the election protocols.
The SC jumped in and required the States to separate the ballots that didn't meet the prior protocols.
The Democratic Governors basically gave the SC the middle finger and kept couniting the votes.
They also made it impossible to categorize which votes were accepted and counted to the previous election protocols.
Now we have millions of votes that have been counted that didn't meet the original state election protocols.
The US SC will not overturn the election or have the states in question hold another election.
And as is evident by how quickly Biden-Harris gained ground when the late arriving votes were counted, most of these votes were for them.
It should also be noted that Trump held a 750,000 vote lead in PA after the early mail in votes and the in person votes had been counted.
So you decide if Trump and the 71 million people who voted for him got screwed.
