Colorado's open gubernatorial seat pits Democratic nominee and state attorney general Phil Weiser against Republican Victor Marx on November 3. Recent polls, including ResearchCo and University of Colorado Boulder surveys from late October and early November, show Weiser leading by 16 to 20 points among likely voters in a state with a consistent Democratic tilt and no GOP gubernatorial win since 2002. Weiser secured the nomination after defeating Senator Michael Bennet in the June primary, while Marx prevailed in a tight Republican contest. Trader consensus on margins clusters around the mid-teens, reflecting these polling averages, the open-seat dynamics after term-limited Governor Jared Polis, and Colorado's partisan fundamentals, though final turnout and any last-minute developments could still adjust the outcome.
