Melat Kiros Upsets 15-Term Rep. Diana DeGette in Colorado Democratic Primary

Melat Kiros, a first-time candidate, defeated 15-term incumbent Rep. Diana DeGette in the June 30 Democratic primary for Colorado’s 1st Congressional District, a deep-blue Denver-area seat where the primary is likely to determine the next member of Congress. The loss ended DeGette’s nearly three-decade run representing the district in the House.

AP-tabulated results carried by NPR showed Kiros with 83,685 votes, or 53.2%, to DeGette’s 62,630 votes, or 39.8%. Wanda James finished with 11,046 votes, or 7.0%. The Associated Press called the race on the night of June 30, according to Colorado Sun reporting that cited the AP call.

Kiros, 29, was described by AP as a lawyer and Ph.D. student making her first run for Congress. She has described herself as a democratic socialist. DeGette had represented the district since January 1997 after first being elected in 1996, making this race her bid for another term after 15 terms in office. James, the third Democratic candidate, finished a distant third.

The result carries unusual weight because Colorado’s 1st District is considered safely Democratic. Ballotpedia and other outlets rated the seat Solid or Safe Democratic, and reporting before and after the primary said the Democratic nominee would be strongly favored in November. In practical terms, Kiros’ primary win puts her in a commanding position to become the district’s next representative.

There were warning signs for DeGette months before Election Day. At the district Democratic assembly in March, Kiros won about 67% of delegate support, while DeGette won about 33%, an early show of strength for the challenger. Colorado’s ballot access system allows major-party candidates to reach the primary either by winning at least 30% support at a district assembly or by qualifying through petition signatures. Kiros and DeGette both made the ballot through the assembly, while James qualified by petition.

Outside spending also underscored the race’s stakes. The Colorado Sun reported that a super PAC spent about $485,000 supporting DeGette, while three super PACs spent roughly $1.3 million in the final months attacking Kiros.

Even so, the final margin made the upset unmistakable: a newcomer ousted a longtime incumbent in one of the state’s bluest districts. That outcome removes a long-serving House Democrat from a seat she had held since the 1990s and hands the nomination to a candidate who ran as a generational and ideological alternative.

Addressing supporters on election night, Kiros said, “We are winning from coast to coast,” and “We are taking back our party and our country!” AP reported that DeGette did not speak or release a statement after the race was called.
