Reilly Neill leads the Democratic primary for Montana’s open U.S. Senate seat due to her superior fundraising and sustained grassroots presence across all 56 counties. As of late March, she held the vast majority of the field’s cash on hand, enabling consistent advertising and voter outreach while opponents remain underfunded. Recent candidate forums and media interviews have reinforced her positioning as a moderate former state legislator focused on health care costs, housing, and direct engagement with voters. The June 2 primary date concentrates attention on these structural advantages, with other candidates such as Alani Bankhead and Michael Black Wolf showing limited resources and visibility that have kept their prospects marginal in trader assessments.
