When Democrats run out of Republicans to cheat, they start cheating other Democrats. The winner of the "election" is always supposed to be the person sanctioned by the State Democrat Central Committee. If they run out of ballots, they will always find more for their preferred candidate.
The only time vote fraud is prosecuted is when some upstart Democrat defies the choice of the Central Committee.
Saw this up close in Pierce and King counties in the State of Washington. I am guessing that it works the same way in California, particularly in Los Angles.
That makes a lot of sense. Thank you for the explanation.
