Phil Weiser secured the Democratic nomination in June by defeating U.S. Sen. Michael Bennet in the primary, positioning the two-term attorney general as the clear frontrunner in Colorado’s open gubernatorial race to succeed term-limited Gov. Jared Polis. Traders assign overwhelming probability to Weiser due to the state’s consistent Democratic lean in recent cycles, its absence of a Republican governor since 2007, and forecasts rating the contest solidly Democratic. Victor Marx’s narrow Republican primary victory over state Sen. Barbara Kirkmeyer has left the GOP nominee with limited cash reserves and no endorsements from primary rivals. Potential shifts remain possible from major late-campaign developments such as national economic changes or unforeseen candidate-specific events before November voting.
