South Dakota was won by formerVice PresidentRichard Nixon (R–New York), with 53.27 percent of the popular vote, against Vice PresidentHubert Humphrey (D–Minnesota), with 41.96 percent of the popular vote.Independent candidateGeorge Wallace would carry five Southern states, but finished with a mere 4.76 percent of South Dakota's popular vote.[2][3] Althoughthe West River region of South Dakota possessed powerful racial conflicts akin to Wallace's native South – although between Whites andNative Americans rather than between Whites andBlacks – significant anti-Southern feeling amongst itsYankee descendants limited Wallace's appeal even there,[4] and inthe East River with fewer Native Americans and a strongScandinavian-American influence,[5] 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 inHyde andSully Counties. Consequently, South Dakota proved Wallace's eighth-weakest state nationally.Davison andHanson counties were the only ones to vote for Nixon in 1968 but in neither 1960 nor 1972, along withRusk County inWisconsin.
^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.
