Verified. This is a 2026 gubernatorial CAMPAIGN promise, and Bennet's official campaign platform frames the "Colorado Clean Air, Affordable Energy Program" — a statewide cap-and-invest program with "a clear, enforceable cap on emissions across major economic sectors" to meet Colorado's "statutory climate targets through 2050" — explicitly as something he would "design and implement" "As Governor." Creating a Colorado state cap-and-invest program requires the governorship (plus the legislature); Bennet's current office (U.S. Senator) has no authority to enact a state program. On June 30, 2026, Bennet LOST the Democratic gubernatorial primary to Attorney General Phil Weiser (AP called it with Weiser leading by ~10 points, roughly 55%-45%). Having lost the primary, he will not be the nominee, will not become governor, and never obtained the office the promise required. There is no alternative pathway from a Senate seat to create a state program, so the outcome is settled rather than not-yet-determinable — he never got a genuine chance to fulfill it. NO_OPPORTUNITY (not ATTEMPTED, because the failure was electoral — he never held the office to even begin; not UNRATABLE, because the primary loss makes the outcome definitively determinable) is correct. Same nonpartisan standard would apply to any candidate whose office-contingent promise was foreclosed by losing the election.
