The 2026 Colorado gubernatorial race features an open seat after term limits on Democratic incumbent Jared Polis, with Attorney General Phil Weiser as the Democratic nominee facing Republican Victor Marx. Trader consensus on the Democrat's margin clusters around 20-35 percent because Colorado's partisan lean favors Democrats modestly while limited general-election polling leaves room for variation based on turnout among unaffiliated voters and suburban areas. Recent primary outcomes, including Weiser's victory over Michael Bennet and Marx's narrow Republican nomination, have not produced fresh head-to-head surveys, sustaining uncertainty ahead of the November 3 vote. Factors that could widen or narrow the margin include final voter mobilization, any late independent candidacies such as Greg Lopez, and national political conditions influencing down-ballot performance.
