Due to a difficult primary petition requirement in South Dakota this year, no Democrat qualified to run for the state’s sole U.S. House seat. This is the first time since 1930 that the Democrats have not had a full slate of nominees for that office. In 1930, when the state had three districts, Democrats had no nominee in one of the three seats.
It is likely that there will be a Libertarian nominee for U.S. House this year. The Libertarian Party is ballot-qualified and nominates by convention. It is also conceivable another new or minor party might get on the ballot in nominate for that office.
