Sen. Tina Smith's announcement last month that she will not seek re-election in 2026 created an open Minnesota Democratic Senate primary, driving trader consensus heavily toward Lt. Gov. Peggy Flanagan at 79% implied probability. Flanagan's high-profile statewide role, early campaign launch with EMILYs List endorsement, and leading position in initial polls among potential candidates have solidified her frontrunner status, reflecting her appeal to key Democratic voting blocs like progressives and women voters. Rep. Angie Craig follows at 16.5% on speculation of a potential bid leveraging her congressional experience, while lower odds for AG Keith Ellison, Rep. Ilhan Omar, and others stem from narrower name recognition or competing ambitions. The August 2026 primary remains distant, with further candidate announcements and fundraising likely to influence odds.
