Declared candidates. Not an open seat: incumbent Gov. Larry Rhoden (R) is running for a first full term (he ascended in Jan 2025 when Kristi Noem became DHS Secretary). The June 2 2026 primary was held but the GOP race is UNRESOLVED: in SD's first-ever gubernatorial primary runoff (35% threshold law), businessman Toby Doeden (1st, ~31%) and incumbent Rhoden (2nd, ~25%) advance to a July 28 2026 runoff; U.S. Rep. Dusty Johnson was eliminated. Dan Ahlers is the sole/presumptive Democratic nominee. The field and its fundraising will keep updating as primaries settle and new FEC reports land.
The rating is grounded in this seat’s record on Akashic — its partisan lean, same-office history, and demographics. Read the full profile on the SD state page.
