The Bagwan Shree Rashneesh (sp?) who took over a small town in Oregon in the early 1980’s, had many followers who all wore red dyed sweat suits, used the voting booth to try to take over even more of the local govt.

He had enough legal residents who were all registered voters. The plan was to sprinkle bacteria on the local salad bar the night before the big election and most of the people who had not voted absentee, would then be too sick to go to vote and his followers would put their own people in the govt.
