PA is already lost. The Demoncrap governor sent out prepaid mail-in ballots to every single voter in the state. Prepaid mail never gets a cancellation stamp, so, there will be as many 'discovered' ballots as is needed to deliver the state... and you can never prove it was returned after the election.
He may have sent them out, but that doesn’t mean they will be used. I got requests in the mail but I never sent even those in.
