Thesis

Minnesota's open Senate seat: Lt. Gov. Peggy Flanagan (DFL) against former broadcaster Michele Tafoya (R), both nominated in the August 11 primary. The number comes from the polls. Eleven public polls since September 4 average Flanagan 50.7, Tafoya 46.9, a 3.8-point lead, and at a 6.5-point polling error that puts Flanagan at 72%. The market prices her higher; we have no evidence the market lacks, since this is a polls-only base with no EHIQ-specific input. No Flanagan-Tafoya debate has been scored, so there is no language read yet.
  1. 1.2026-10-18Polls (11, Sep 4 to Oct 18; 7-day half-life, sample-size weighted): Flanagan 50.7, Tafoya 46.9, margin +3.8. Newest: Trafalgar Oct 13-15, KSTP/SurveyUSA Oct 8-12.
  2. 2.2026-10-18Win probability: margin / 6.5-point polling error (FiveThirtyEight Senate error since 1998) gives Flanagan 72%.
  3. 3.2026-10-18Language: commentary only. No general-election debate listed as of Oct 18.
