1 House, 1 Senate and 1 governor; none is rated a toss-up or leaning to a party (Cook Political Report ratings, entered by the lab).
Statewide races
A Senate race and a governor’s race are on the 2026 ballot. Once a primary is called, only the candidates recorded as advancing are listed; before that, everyone running.
Each race links to its own page: the candidates, what they say and the money they report. Cook Political Report ratings, entered by the lab (last updated by the lab on Jun 24, 2026); a forecaster’s judgement about the general election, not the lab’s.

What the candidates say
Eight of South Dakota’s 12 candidates have 10 or more classified statements. Eight have 50 or more and are ranked against candidates nationwide.
An AI model reads each statement and marks the kinds of statement it contains; a candidate’s rate is the share of their statements with that label. Incumbent members of Congress are measured on everything they publish in office, everyone else on posts on X. A rate describes what was said, not whether it was right.
