Most of the fraud occurs in states traditionally held by Democrats. Fun fact and tinfoil hat fantasy, if we used the method of whoever wins the most counties in a state gets the Electoral Votes, the Democrats would never win another election.
“Most of the fraud occurs in states traditionally held by Democrats.”
We all know about the vote harvesting in Orange County California, but do you mean states like Nevada or Arizona or Georgia or Alabama or Virginia or Kentucky or ... do you get the picture now?
IOW, it doesn't matter if Trump loses Calif by 10,000 votes or 10 million votes. Same true for NY & IL. He could lose the national popular vote by 20m, and yet still come out with a higher EV total than 2016.
So, the key isn't electoral fraud per se, but preventing/managing electoral fraud in states that matter. That's why while I don't see Trump wasting his time in Calif, he's probably making damn sure that the tighter, keystone states are under strict scrutiny.
