He was a U.S. Presidential candidate for four consecutive elections, in which he sought the Democratic Party nomination in 1964, 1972, and 1976, and was the American Independent Party candidate in the 1968 presidential election. He remains the last third party candidate to receive a state's electoral college votes.
