Minnesota's open Senate seat, vacated by retiring Democrat Tina Smith, features Democratic Lt. Gov. Peggy Flanagan against Republican Michele Tafoya in a state that favored Kamala Harris by four points in 2024 and has not elected a Republican senator since 2002. Flanagan secured the nomination with 59% in the August primary, backed by progressive endorsements, while Tafoya won her party's contest as a political outsider. Recent polling averages show a narrow Flanagan edge of roughly two points amid debates over state fraud cases, education outcomes, and crime trends during the current Democratic administration. Prediction market pricing reflects the structural Democratic advantage and historical patterns over the tight survey results, with the November 3 general election still weeks away.
