Democratic voters in several U.S. states participated in primaries on August 11, 2026, as the party's left faction seeks to maintain momentum ahead of the November elections. In Minnesota, Lieutenant Governor Peggy Flanagan is competing against Congresswoman Angie Craig for the Democratic nomination to succeed retiring Senator Tina Smith. Flanagan has received endorsements from Smith and leftist senators such as Bernie Sanders and Elizabeth Warren, while Craig's supporters emphasize her experience in winning competitive elections.
Flanagan criticized special interest spending in the race, stating that $20 million has been spent to influence the outcome. The primary reflects broader tensions within the Democratic Party regarding its direction, particularly in light of President Donald Trump's low approval ratings. Immigration policy has become a contentious issue, with Flanagan attacking Craig for her support of a Republican-backed immigration measure.
In Wisconsin, Democratic socialist Francesca Hong is viewed as the frontrunner for the gubernatorial nomination, despite concerns from some establishment Democrats about her electability in a closely divided state. Milwaukee County Executive David Crowley is the main moderate alternative in the race. The outcomes in these primaries could impact the party's strategy as it seeks to regain control of Congress.
In South Carolina, Republican Senator Darline Graham, who was appointed to fill her brother's seat, is vying for a full term with the endorsement of Trump. She faces challengers including Congressmen Ralph Norman and Russell Fry, and former Governor Mark Sanford. A runoff is expected if no candidate secures a majority in the primary.
