What’s Happening

The Democratic primary for Colorado’s 1st Congressional District has intensified as challenger Melat Kiros, a 29-year-old democratic socialist, appears poised to unseat 30-year incumbent U.S. Rep. Diana DeGette. According to a June 26 report from The Colorado Sun, Kiros has tapped into national discontent with incumbents among Democratic voters, leveraging a savvy social media operation to build a campaign that has DeGette’s supporters “incredibly nervous.” The race represents the most serious challenge DeGette has faced since she was first elected to represent Denver in 1996. Kiros’s surge has been fueled by progressive grassroots energy, with local Democratic Socialists of America chapters mobilizing volunteers ahead of the primary vote. [The Colorado Sun, Jun 26]

The contest has drawn national attention as a bellwether for the progressive wing’s strength in 2026 midterm elections. Axios reported on June 24 that progressive candidates in Colorado are hoping the “aftershock” from a political earthquake in New York City—where incumbents were ousted in recent primaries—will reach Denver next week. Colorado secretary of state candidate Amanda Gonzalez, backed by the DSA, noted that the New York results serve as a warning to establishment Democrats. The primary election is scheduled for June 30, with mail ballots already distributed to voters. Kiros’s campaign has focused on Medicare for All and housing affordability, contrasting with DeGette’s more centrist record on healthcare and energy policy. [Axios, Jun 24]

The outcome of the Melat Kiros Democratic nominee for CO-01 race will determine whether Denver sends its first democratic socialist to Congress. If Kiros wins the primary, she will be heavily favored in the general election for the safely Democratic district. The race has also become a proxy fight between national progressive groups and the Democratic establishment, with outside spending on both sides. DeGette has outspent Kiros on television advertising, but Kiros has closed the gap through digital organizing and small-dollar donations. The final vote count is expected by late July 1, with turnout likely boosted by competitive statewide primaries for U.S. Senate and attorney general. [Axios, Jun 23]
