This time it's US Democrats defrauding each other in a highly Democratic part of Texas, the Rio Grande Valley. In the minority urban centers of the northeast and midwest they call it street money or walking around money. In spanish dominated Texas, they instead of referring to the money, it's the people who deploy it, the politiqueras, that define the practice. In either case, it's notoriously vulnerable to corruption. Three politiqueras have been arrested by the FBI for vote buying and a mysterious suicide followed soon after.
But the US has no voter fraud problem. The system is working just fine according to the Democratic party.
