Peggy Flanagan secured the Democratic nomination for Minnesota’s U.S. Senate seat in the August 11, 2026 primary, defeating Rep. Angie Craig and lesser-known challengers after receiving the state DFL endorsement and support from retiring Sen. Tina Smith. As lieutenant governor since 2019, Flanagan consolidated progressive and party infrastructure backing in a contest that highlighted tensions between the party’s left and moderate wings, with turnout and endorsements favoring her path in a state where Democrats hold structural advantages. The primary’s decisive outcome has produced near-certain trader consensus on her nomination, though formal certification or any late procedural challenges could theoretically alter the result before market resolution.
