Just about every case of voter fraud I've read about here the last few years has been:
Dems registering more voters than what the population is in certain counties
Dem campaign workers forging signatures.
Dem campaign workers throwing out ballots or hiding Military votes
Dems campaign workers filling out mail in ballots for people in republican districts.
Dem voters filling out ballots for dead spouses/girlfriends.
Dems want to allow illegal immigrants to vote
Dems want felons to be allowed to vote
Dem secretary of state purging republican voters without cause.
Dems ------- Bernie and his supporters right in the ass......and the money donors PROVEN that dems screw their own
