Religious demagogue whose followers overthrew the United States government and instituted a theocracy. This dictatorship controlled the country for several generations until it was itself overthrown by resistance movements. His followers included Venus colonials, but the movement apparently was dominant only in the United States. He is also called the Prophet. He was elected President in 2012, with 27 percent of the popular vote (votes were cast by 63 percent of registered voters, who were less than half of those eligible to vote) but 81 percent of the Electoral College votes.
