South Dakota's electoral votes in U.S. presidential elections 1892-2020
As of 2020, no U.S. president has come from South Dakota, although both Democratic nominees in the 1968 and 1972 elections, former vice president Hubert Humphrey and George McGovern respectively, were born in South Dakota; despite this, Richard Nixon carried South Dakota on both occasions. For most of its history, South Dakota was allocated four electoral votes; this number did peak at five votes between 1912 and 1928, however it has been at just three since 1984, which is the lowest possible number.
