Colorado 2026 Primary Election Results

Colorado completed its primary elections on Tuesday, June 30. The contests unfolded against a dynamic backdrop, with the state’s increasingly blue and unaffiliated electorate reacting to a second Trump term. More locally, a wide swathe of Colorado’s Democratic electorate are also railing against Gov. Jared Polis’ (D) decision to pardon former Mesa County Clerk and election denier Tina Peters.

Overall, Democratic progressives were able to channel what appeared to be growing angst against perceived “establishment” candidates for a series of notable wins. Sitting Attorney General Phil Weiser defeated senior U.S. Senator Michael Bennet to run in the November election. As well, political newcomer and self-described Democratic Socialist Melat Kiros surpassed 29-year incumbent Dianna DeGette in the 1st Congressional District.

Also, with Colorado opening its primaries to unaffiliated voters several years ago—the largest voting bloc in the state—they again heavily influenced a number of key contests. Unaffiliated registrations now represent 50.5% of active registrations, and candidates for statewide office in particular expressed the need to appeal to those voters. That segment of the electorate will also be a deciding factor in the general election, which is only four months away.

The following is a summary of the results from the primaries for federal, statewide and state legislative seats.
