This year, the South Dakota Libertarian Party has seven legislative nominees on the ballot. That is the most that any party in South Dakota has had, other than the Republican and Democratic Parties, since 1928.
All of the seven Libertarians are running for State Senate; none are running for State House.
South Dakota had a very strong Farmer-Labor Party in the 1920’s, but it went off the ballot after 1928. In 1924 it elected a State Senator in South Dakota, and polled 13.3% for Governor.
