Despite the state's general Republican and conservative leanings, Democrats have found success in various statewide elections, most notably in those involving South Dakota's congressional representatives in Washington. American Indians have been becoming more active in state and county electoral politics. In the 2002 election, American Indian voting carried Tim Johnson as the Democratic candidate by a margin of 532 votes. Until his electoral defeat in 2004, Senator Tom Daschle was the Senate minority leader (and briefly its majority leader during Democratic control of the Senate in 2001–02). Other prominent South Dakota Democrats include former presidential nominees George McGovern and Hubert Humphrey.
