Whoever wins the Republican primary becomes the GOP nominee for South Dakota governor and is the heavy favorite in the general election in a reliably Republican state.
The nominee will set state policy on taxes, energy, abortion access, and education and will shape the executive agenda for the next four years.
Dusty Johnson, Larry Rhoden, Jon Hansen, and Toby Doeden are the principal contenders in the Republican primary.
Johnson is a U.S. representative with statewide name recognition. Rhoden is the lieutenant governor, Hansen is a state representative, and Doeden runs a smaller campaign with local support.
Campaign fundraising, advertising, and endorsements from national figures or the state GOP will shift probabilities between now and the vote.
Voter concern about agriculture, energy prices, the state budget, and social issues, plus turnout differences between rural counties and Sioux Falls, will determine momentum.
Early polls, candidate debate showings, and fundraising filings in early 2026 will indicate who is consolidating support.
Pay attention to Trump or national GOP endorsements, state party signals and county convention results, plus vote-by-mail and turnout reports in the weeks before the primary.
