Montana Democratic Party chair Shannon O’Brien quit Monday and endorsed independent Seth Bodnar over Democrat Alani Bankhead, saying her own nominee cannot win.

O’Brien announced the resignation and the endorsement in an MS Now op-ed, making plain that she no longer trusts the party’s Senate pick to carry Democratic values or defeat Republican Kurt Alme in November. The Washington Examiner reported the break as a public rebuke of Bankhead’s campaign strength and her willingness to take counsel.

In the op-ed, O’Brien said Bankhead “does not have the momentum, resources or will to win this race.” She framed the choice as duty rather than personal preference.

"I’m a person with a positive outlook. I’m uncomfortable being negative about anyone, especially a Democratic nominee,"

O’Brien wrote, then added the harder line that followed.

"But sometimes it’s impossible to stay quiet; sometimes you have to make people uncomfortable for the greater good. The winner of this race will almost certainly vote on a nominee to the Supreme Court. And there are real questions about Democrat Alani Bankhead’s commitment to protecting a woman’s right to choose, her support of working people and her views of people living in poverty."

She also accused Bankhead of “mudslinging at Bodnar, a decent human being,” and said the nominee never sought a conversation on shared values during the months both women held their posts. O’Brien wrote that Bankhead “has refused advice from experienced business and political leaders around the state.”

For a candidate she described as almost brand new to Montana, that stance struck her as “puzzling and jarring.” She pointed to an affordability crisis, rising fuel prices, and what she called an inexplicable war, and said Montanans need people willing to listen. Bodnar, she said, is “someone who listens,” and “is kind, hardworking and bright.”

Her bottom line was institutional: “My job has always been to advance the values Democrats in this state care about,” and “right now, the clearest path to doing that runs through an independent candidate.” The same pattern of party strain has shown up elsewhere, including when a Brooklyn Democratic chair stepped down amid prolonged internal turmoil.

Bankhead fires back at her own party chair

Bankhead did not accept the critique. She said O’Brien had “been working against” her and cast the resignation as an end-run around Montana Democrats who already chose their nominee.

"This summer she got a legal opinion, without a vote of her own board, on whether the party could refuse to replace me if I quit, and her own board members wanted her performance reviewed for it,"

Bankhead said. She continued:

"Now she’s using her exit to campaign for a man who never ran in our primary. Montana Democrats chose their nominee, and Montanans are voting right now."

Bankhead had already refused in August to drop out of the three-way race to clear a path for Bodnar. That refusal left Democrats split while Alme held the Republican lane. Similar party fractures have pushed other Democrats toward outside alliances, much as Fetterman turned toward a Republican ally when pressure rose inside his own caucus.

Poll numbers leave Democrats far behind

A Montana Free Press-Rutgers Eagleton poll released last month underscored the math O’Brien cited. Alme led Bodnar by 8 points. Bankhead trailed Alme by 22 points. In a three-way contest heading toward November, those gaps are not abstract.

O’Brien warned that a win for Alme would install what she called a “puppet” for President Donald Trump and another “automatic yes-man” alongside Sen. Tim Sheehy (R-MT). Those are her labels, not settled fact. What is settled is that the sitting Democratic chair quit rather than defend her party’s nominee against that Republican field. When party machinery fails to hold its own bench, voters notice, just as some Hollywood Democratic helpers have walked away while the left wing tightens control.

Bodnar claims a broader coalition

Bodnar welcomed the endorsement and said he was “deeply grateful.” On X he argued the race already crosses old lines:

"Montanans of every political stripe are coming together in this race because they know what’s at stake, and they’re ready to send an Independent senator to Washington who answers only to them."

Former Democratic Sen. Jon Tester has also endorsed Bodnar, adding another high-profile Democrat willing to skip the party’s official nominee. Cross-party fundraising and network moves have become more common in these fractures, including cases where a Democrat’s campaign tapped Republican donor networks to stay solvent.

The Montana Democratic Party now faces a public split at the top while ballots are already moving. O’Brien’s exit is not a quiet personnel change. It is an open verdict on Bankhead’s viability and on the party’s ability to keep its own leaders aligned. Primary challenges and internal revolts elsewhere, such as talk of a Pennsylvania Democrat eyeing a 2028 challenge, show the same stress lines running through the broader coalition.

When a state party chair resigns and tells voters the independent is the real path to Democratic priorities, the party’s problem is no longer messaging. It is credibility with the people who still have to live with the result.
