Phil Weiser upsets Michael Bennet to win Democratic primary for Colorado governor

Key Takeaways:

• Attorney General Phil Weiser defeated Sen. Michael Bennet in a surprise primary result.
• Democrats have ruled statewide Colorado politics for more than a decade.
• Weiser’s combative posture toward President Trump included filing over 65 lawsuits.
• Bennet had strong name recognition and resources but fell short in shifting voter sentiments.
• This outcome removes the possibility of any appointment or special election for Bennet’s Senate seat.

A Surprising Result

In one of Colorado’s most unexpected political turns in recent memory, Colorado Attorney General Phil Weiser clinched the Democratic nomination for governor, surpassing U.S. Sen. Michael Bennet with a 55% to 45% margin. The Associated Press called the race for Weiser less than an hour after polls closed, reflecting what many see as a decisive shift among Democrats toward fresh leadership.

Two Democratic Heavyweights

The primary matchup pitted two formidable contenders: Bennet, whose tenure in Washington and a 2020 presidential bid earned him both recognition and funding, and Weiser, a well-known figure at the state level as Colorado’s attorney general. Bennet’s extensive experience made him a presumed frontrunner, but the result showed that even high-profile incumbents can face voter discontent linked to national politics.

Fighting Washington

Weiser’s campaign centered on a self-described role as a “fighter” against President Trump, backed by more than 65 lawsuits his office filed challenging the administration’s policies. This combative approach, combined with a progressive shift in the closing weeks of the campaign, energized local Democrats who were looking for a more forceful response to federal actions they opposed.

The Bigger Picture

For over a decade, Democrats have maintained a strong grasp on Colorado’s statewide offices. Weiser’s victory underscores a broader alignment among the party’s voters who increasingly favor candidates willing to confront Republican-led initiatives at the national level. Meanwhile, Bennet’s defeat ends any speculation about a possible opening or special election to replace him in the Senate, where he has two years left on his current term.

What’s Next for Colorado

Given the state’s left-leaning tendencies in recent statewide contests, Weiser now heads into November as the early favorite. The primary’s outcome demonstrates a tilt toward progressive candidates and signals that Colorado voters expect their next governor to stand firm against federal policies they perceive as harmful. As the general election approaches, the race will test how enduring these voter priorities are and how much further Colorado might shift on the political spectrum.
