What races are on the ballot in South Dakota in 2026?
South Dakota's November 3, 2026 ballot includes governor, the US Senate seat held by Mike Rounds, the state's at-large US House seat, and statewide executive offices such as attorney general, whose party nominees are chosen at June conventions. State legislative seats are also up. The Republican gubernatorial nominee will be decided in a July 28 runoff between Toby Doeden and Larry Rhoden.
How does South Dakota's primary work?
South Dakota held party primaries on June 2, 2026. Republican primaries were limited to registered Republicans, while the Democratic primary also admitted independent and unaffiliated voters. For governor, US Senate and US House, a candidate needed at least 35 percent to be nominated outright; because no governor candidate reached that mark, the top two advanced to a July 28 runoff.
Why is the 2026 South Dakota Governor race important?
The 2026 race decides who leads South Dakota after an unusual succession: Larry Rhoden became governor in January 2025 when Kristi Noem joined the federal cabinet, and he must now win the state's first primary runoff on July 28 against Toby Doeden to stay on the ballot. The runoff winner faces Democrat Dan Ahlers in the November 3 general election.
