Phil Weiser Wins Democratic Primary for Colorado Governor, Defeating Michael Bennet

Phil Weiser, the Colorado Attorney General, won the Democratic primary for governor, defeating incumbent Senator Michael Bennet on July 1, 2026. This outcome prevents Bennet from transitioning from the Senate to the governor's office and positions Weiser as a strong candidate for the general election, where Democrats have historically performed well in Colorado. Weiser's victory is considered a significant upset in a closely watched primary race. Bennet is expected to remain in the Senate, avoiding a potential vacancy. Weiser received endorsements from various local officials and progressive organizations, while Bennet had the backing of over 200 leaders from the Colorado Democratic establishment. The Republican primary is being led by Barb Kirkmeyer, who will face challenges in the general election against Weiser.
