—
Progressive upstart Melat Kiros completed a monumental upset https://www.axios.com/local/denver/2026/06/17/attack-ads-political-collusion-1st-district-primary" target="_blank">over U.S. Rep. Diana DeGette, defeating the 15-time incumbent on Tuesday to secure the Democratic nomination in Colorado's 1st Congressional District, the https://x.com/AP_RaceCalls/status/2072169343215870142?s=20" target="_blank">AP reports.
Why it matters: The 29-year-old's victory proves that anti-establishment https://www.axios.com/2026/06/24/mamdani-lander-valdez-chevalier-espaillat-goldman" target="_blank">victories in New York City can be replicated, likely increasing anxiety for other Democratic incumbents.
State of play: Kiros' victory in the deep-blue district means she's poised to https://www.axios.com/local/denver/2026/04/02/progressive-challenger-kiros-tests-degette-primary" target="_blank">become the first Black woman to represent Colorado in Congress and just the third woman to represent the district since 1972.
- The Associated Press called the race for Kiros just after 10pm Tuesday.
- She led by 6 points in latest ballot drop from Denver Elections Division, with 49% compared to DeGette's 44%.
- https://www.axios.com/local/denver/2026/04/22/wanda-james-1st-congressional-district" target="_blank">Challenger Wanda James was in third with 7.2%.
By the numbers: The primary attracted https://www.axios.com/local/denver/2026/06/22/big-money-colorado-democratic-races-june-primary" target="_self">millions in outside spending, according to Federal Election Commission filings.
But despite DeGette's significant financial edge, Kiros prevailed.
- Justice Democrats' super PAC was Kiros' biggest backer, spending more than $500,000, followed by left-wing PAC American Priorities at $150,000.
- Pro-Choice Majority Action — which has ties to the Democratic Women's Caucus and, indirectly, AIPAC — was DeGette's biggest spender, putting more than $1.5 million behind the incumbent.
Context: Kiros earned backing from key left-leaning groups such as the local Democratic Socialists of America chapter, the Colorado Working Families Party, https://www.axios.com/2025/01/14/justice-democrats-primary-challenges-jeffries" target="_self">Justice Democrats and the Sunrise Movement.
- She received a major endorsement from progressive champion Sen. Bernie Sanders (I-Vt.) this month.
- Despite being a Congressional Progressive Caucus member and Medicare-for-All cosponsor, DeGette https://www.axios.com/2026/06/29/colorado-degette-melat-kiros-democrats-election" target="_blank">had been tagged by the left as a defender of Israel and recipient of corporate PAC support.
What's next: Kiros moves on to the Nov. 3 general election, where she's the presumptive winner in the heavily Democratic seat covering Denver and parts of Arapahoe County.
