Reilly Neill holds the leading position in Montana’s June 2 Democratic U.S. Senate primary, driven by her commanding fundraising edge and established statewide profile as a former legislator. She reported over $900,000 raised through March with substantial cash on hand, far exceeding rivals, enabling broad ground outreach and community roundtables across the state. Recent independent expenditures, including a new PAC directing hundreds of thousands toward Alani Bankhead and opposing Neill, have introduced late visibility for underfunded candidates, yet the primary’s proximity limits their reach. Lower probabilities for Bankhead, Michael Black Wolf, Michael Hummert, and Kathleen McLaughlin reflect their limited resources and narrower campaign footprints. Trader consensus aligns with these structural advantages ahead of the vote.
