Recent reporting and announcements directly related to this race and its candidates.
South Dakota’s Senate race remains centered on Sen. Mike Rounds after the Democratic nominee withdrew. Rounds is now facing only independent Brian Bengs, and the latest reporting highlights a policy question over Wounded Knee medals rather than a major shift in the race. The race still looks heavily tilted toward the Republican nominee, with the Democratic field cleared out. The latest news is unlikely to change that much, though it keeps the contest focused on Rounds versus an independent.
