Reilly Neill's commanding 91.5% implied probability in the Montana Democratic U.S. Senate primary reflects her advantages as a former state representative with strong name recognition, leading Democratic fundraising totals, and a splintered field of underfunded challengers like Alani Bankhead and Michael BlackWolf ahead of the June 2 vote. Recent GOP super PAC mailers from More Jobs, Less Government—highlighting Neill's opposition to President Trump and labeling her "too liberal for Montana"—aim to boost her nomination as a perceived weaker general election foe against incumbent Steve Daines, but have instead rallied Democratic support through inbound calls to her campaign. An upset would require late challenger consolidation, a major Neill scandal, or party endorsement shift, though structural barriers favor her dominance.
