You make the erroneous assumption here that the maximum number of ballots cast is limited by the number of registered Pennsylvania voters.
@Hoodat That has always been true of Philly. In one recent election,the Dims in Philly were actually accusing the Republicans of voter fraud because the Dim candidate ONLY pulled in something like 103 percent of the registered vote.
No kidding. They were genuinely upset about it,too.
Evidentially,neither math nor reality is a part of their lives.
