South Dakota politics are generally dominated by the Republican Party. Since statehood, Republicans have carried the state's electoral votes in all but five presidential elections: 1896, 1912 (by Theodore Roosevelt's Progressive Party), 1932, 1936 and 1964. (Democrat George McGovern—a native South Dakotan—failed to carry his home state in 1972.) Only Alaska has been carried fewer times by a Democrat. Additionally, a Democrat has not won the governorship since 1974. As of 2016, Republicans hold a 15% voter registration advantage over Democrats and hold large majorities in both the state House and the state Senate.
