Association with the KKK destroyed David Duke’s political ambitions. During the 1988 presidential election, Duke’s sole victory was in the New Hampshire vice presidential primary. Running in 11 states on the Populist ticket, he won just shy of 50,000 votes–in a race that saw 91.5 million votes cast. Libertarian candidate Ron Paul got 10 times Duke’s vote tally.
