- Open seat: incumbent Dusty Johnson (R) is not seeking re-election to the House and withdrew from this race, running instead for Governor of South Dakota in 2026. Marty Jackley, the sitting South Dakota Attorney General, defeated James Bialota 79.2%-20.8% in the June 2, 2026 Republican primary (Casey Crabtree and Dusty Johnson also withdrew from that primary). Nicole Gronli (also known as Nikki Gronli) advanced unopposed after South Dakota's Democratic primary was canceled. Jack Pittman (independent) did not make the general-election ballot.[1]

Issue evidence — side by side
Recorded votes, documented positions and candidates’ own words are shown with sources. “In their own words” quotes a candidate on the topic without inferring a stance. Votes describe specific bills or motions; they do not establish overall support or opposition to a broad issue. A dash means our research has no evidence on that topic, not that the candidate has no position.
