Gov. Larry Rhoden, who replaced Kristi Noem last year when President Donald Trump nominated her to lead the Department of Homeland Security, was battling with Rep. Dusty Johnson and former state House Speaker Jon Hansen for a second spot in the July 28 runoff. The primary will go to a runoff because no candidate eclipsed 35% of the vote.

Trump did not issue an endorsement in the race. Doeden branded himself on his campaign website as “a total political outsider who’s tired of the government’s failure to deliver on its promises” and one of Trump’s “fiercest supporters.”

Rhoden, a former lieutenant governor, agriculture secretary and lawmaker, campaigned on property tax cuts and lowering crime in his bid for a four-year term.

Johnson is the state’s lone representative in the House, where he previously was chair of the Republican Main Street Caucus. Hansen, who was elected to the South Dakota House in 2010, held several leadership positions before he became speaker.

The Republican nominee will be the favorite to win the general election in the solidly red state this fall. A Democrat has not served as governor in South Dakota since the 1970s, and Trump carried the state by 29 points in 2024.
