Thanks for posting this. I’ve been posting it in dribs and drabs since 2020, but this shows what happened quite clearly. Montgomery County was ground zero for vote fraud in PA in 2020. I’m guessing that those 66K found votes for Biden were mostly manufactured.
My daughters and their families live in eastern Montco. They told me the lines at the polls were tremendous in 2020 (despite the state sending mail in ballots to all) and those in person voters were not waiting in line to vote for Biden.
