Montana Democratic Chair Resigns to Back Independent Bodnar, Criticizing Bankhead

Key points

• Shannon O'Brien resigned as Montana Democratic Party chair effective immediately on October 12, 2026, to endorse independent candidate Seth Bodnar for the U.S. Senate.
• O'Brien criticized Democratic nominee Alani Bankhead for refusing to engage with party leaders and questioned her commitment to protecting reproductive rights and supporting working people.
• O'Brien joined other prominent Montana Democrats, including former senators Jon Tester and Max Baucus, in endorsing Bodnar over Bankhead.
• Bankhead responded by stating O'Brien had been working against her for months and that Montanans had already chosen their nominee in the primary.
• The race is for the U.S. Senate seat held by Republican Steve Daines, who is not seeking reelection; the Republican nominee is former U.S. attorney Kurt Alme.

Background

This development follows a pattern of intra-party conflicts in Democratic leadership, such as the Brooklyn Democratic Party chair stepping down amid court challenges in September 2026. It also mirrors recent instances of Democratic leaders defying party lines, like California Governor Gavin Newsom endorsing Proposition 42 in October 2026 to block a billionaire tax, despite opposition from his party.

How outlets are covering it

KECI and The Washington Post reported the resignation and endorsement, noting O'Brien's criticism of Bankhead's alignment with Democratic values. MS NOW published O'Brien's op-ed detailing her reasons, including concerns about Bankhead's refusal to listen to advice and her perceived lack of momentum. Bankhead, as reported by The Washington Post, countered that O'Brien was using her exit to campaign for a candidate who did not run in the primary, emphasizing that the party had already chosen its nominee. The outlets highlighted the deep division within the Montana Democratic Party, with some leaders alleging Bankhead is a Republican plant, while Bankhead's camp framed the resignation as a long-standing political maneuver against her.

Why it matters

The resignation of a key party leader and the endorsement of an independent candidate signal significant internal fractures within the Montana Democratic Party. This could impact voter turnout and strategy in a competitive U.S. Senate race, potentially affecting the balance of power in the Senate and the broader political landscape in Montana.

What to watch

The race will continue with Alani Bankhead, Seth Bodnar, and Kurt Alme as the main candidates. The impact of O'Brien's endorsement on undecided voters and the overall campaign strategy for the Democratic side will be closely monitored in the lead-up to the election.
