There was tons of fraud just not the type of fraud you’re expecting. When state supreme courts change election law as they did in at least two states to:
-allow mail in ballots to be counted after Election Day
-allow mail in ballots to be counted that had mismatched or no signature at all
-allow mail in ballots to be counted that had no postmark
that’s judicial fraud.
Specifically, in PA, the state legislature and ONLY the state legislature were enumerated with the power to make/change/amend election laws. Pennsylvania’s constitution is very clear about that.
Point being, there’s always going to be some level of fraud, however, it’s not enough to sway the results
