6/30/2026, 7:12:35 AM
Core Contest
On June 30, 2026, 29-year-old democratic socialist Melat Kiros challenges 15-term incumbent Rep. Diana DeGette in Colorado’s 1st Congressional District Democratic primary. Kiros, a former attorney dismissed in 2023 after a letter criticizing Israel, runs under the Democratic Socialists of America. DeGette, 68, has represented the Denver-area seat since 1997.
Progressive Momentum
The contest follows DSA wins in New York, where mayoral and congressional candidates backed by Mayor Zohran Mamdani unseated incumbents. DSA co-Chair Ashik Siddique said those victories show the direction the country is heading. Colorado is the next test.
Candidates, Endorsements & Funding
Kiros has a Bernie Sanders endorsement and $515,000 from Justice Democrats; DSA volunteers are canvassing Denver. DeGette is backed by Pro-Choice Majority Action, which has spent over $1.5 million on ads. Total outside spending totals $3.1 million, with roughly $2.4 million favoring DeGette and $665,000 for Kiros. Local polls show a neck-and-neck race, some giving Kiros a slight edge.
Policy Divergence
Both candidates support Medicare for All, universal childcare, and defunding ICE. They diverge on Israel: DeGette backs a two-state solution; Kiros says Israel should cease to be a Jewish state, calling it an ethnocracy. Kiros also attacks DeGette’s corporate PAC donations.
Statements & Criticism
DeGette warned that the party cannot afford to send an inexperienced candidate to Washington, emphasizing her record as an impeachment manager. Kiros said she could not determine the perpetrator’s motives, labeling the Boulder firebombing a hate crime but not definitively antisemitic. State Sen. Julie Gonzales and Rep. Yara Zokaie, both Democrats, condemned Kiros for not calling the attack antisemitic, calling it a missed chance for community healing.
Conflicting Reports & Gaps
Kiros calls the Boulder attack a hate crime but stops short of labeling it antisemitic; Jewish leaders uniformly call it antisemitic. Polling data are limited, with no statewide surveys released. The effect of Kiros’s critique of corporate PACs on voter behavior remains unmeasured.
Verbatim Quotes
- “When you’re living through these kinds of moments on such a regular basis, it feels impossible to be able to change course and believe your vote actually makes a difference,” — Melat Kiros, candidate
- “I don’t know what was in the heart of the perpetrator,” — Melat Kiros, 9News interview
- “Now is not the time to gamble and send somebody with no experience to Washington,” — Diana DeGette, campaign statement
- “The answer is obvious that the attack on Jewish people in Boulder was an antisemitic attack and a horrific act of violence that all leaders should condemn.” — Julie Gonzales, state senator
What’s Next
The June 30 primary will reveal whether a DSA-aligned challenger can unseat a long-standing Democrat in a solidly blue district. A Kiros win could broaden progressive insurgency in the Mountain West; a DeGette victory would reaffirm incumbent strength.
