Great, so now this gives extra credence to the "the election was stolen" narrative. Well, I mean it looks like in this case it had actually been stolen for years in that particular ward in Philly.
Hopefully one day we can have paper trails, IDs, registration records matching and so on. We can fly satellites beyond the solar system, but managing voting integrity of a few hundred million people is seemingly unsurmountable problem. Every single election it's an endless tirade of debates afterwards that it was stolen or not stolen and so on. This is stuff that even poorer countries with even more people seem to manage.
