Phil Weiser secured the Democratic nomination in June 2026 by defeating U.S. Sen. Michael Bennet in the primary, positioning the sitting attorney general as the clear frontrunner to succeed term-limited Gov. Jared Polis in the solidly Democratic state. Colorado has not elected a Republican governor in more than two decades, and recent fundraising reports show Weiser maintaining a substantial cash advantage over Republican nominee Victor Marx heading into the final weeks. Marx, who emerged from a close three-way primary, has faced scrutiny over campaign finance matters and limited general-election support from some party figures. Trader consensus at 96.5% for Weiser reflects these structural and resource imbalances, though late developments such as major scandals, shifts in national sentiment, or unusually high turnout in Republican strongholds could still narrow the margin before November 3.
