South Dakota was won by former Vice PresidentRichard Nixon (R–California), with 53.27% of the popular vote, against Vice President Hubert Humphrey (D–Minnesota), with 41.96% of the popular vote. Independent candidate George Wallace would carry five Southern states, but finished with a mere 4.76% of South Dakota's popular vote. Although the West River region of South Dakota possessed powerful racial conflicts akin to Wallace's native South – although between Whites and Native Americans rather than between Whites and Blacks – significant anti-Southern feeling amongst its Yankee descendants limited Wallace's appeal even there, and in the East River with fewer Native Americans and a strong Scandinavian-American influence, Wallace possessed generally insignificant appeal. Although he performed reasonably in some West River counties, within the more populous East River Wallace cracked half his national percentage (6.75%) only in Hyde County, and consequently South Dakota proved Wallace's eighth-weakest state nationally.
^Although he was born in California and he served as a U.S. Senator from California, in 1968 Richard Nixon’s official state of residence was New York, because he moved there to practice law after his defeat in the 1962 California gubernatorial election. During his first term as president, Nixon re-established his residency in California. Consequently, most reliable reference books list Nixon's home state as New York in the 1968 election and his home state as California in the 1972 (and 1960) election.
