NBC News projects Phil Weiser has won the Colorado Democratic gubernatorial primary, beating Michael Bennet

NBC News has projected that Colorado Attorney General Phil Weiser has won the state’s Democratic gubernatorial primary, defeating U.S. Senator Michael Bennet. According to a recent poll commissioned by Weiser’s campaign, 45% of likely Democratic primary voters support Weiser, compared to 36% for Bennet, with 19% remaining undecided. The survey, conducted by Public Policy Polling, included 600 likely Democratic primary voters and had a margin of error of 4 percentage points.

As of June 25, 2026, 500,000 voters had cast ballots in Colorado’s primaries, with approximately 200,000 of those being unaffiliated voters. Most unaffiliated voters who had returned ballots opted to participate in the Democratic primary. County clerks anticipate a surge in mail-in ballots over the weekend and into early next week, a common pattern in Colorado elections.

The outcome of the primary will influence the broader political landscape in the state and could impact future policy priorities and campaign fundraising dynamics.
