Melat Kiros, a 29-year-old democratic socialist, won the Democratic primary for Colorado's 1st Congressional District, defeating 15-term incumbent Diana DeGette on July 1, 2026 [1, 2, 3, 4, 5]. Kiros captured approximately 49% of the vote compared to DeGette’s roughly 44%, with the race called after 78% to 84% of ballots were counted [2, 4, 5, 6].

Born in Ethiopia in 1997, Kiros moved to the US as an infant. She graduated from Notre Dame Law School in 2022. She drew controversy after being fired by a New York law firm over refusing to remove a social media post critical of Israel [1, 3, 7, 8, 9]. Kiros has accused Israel of genocide against Palestinians in Gaza and called for a US arms embargo, positions that sharply contrast with DeGette’s stance [1, 2, 3, 7, 8, 9, 6].

DeGette, 68, a member of the Congressional Progressive Caucus, supports Medicare-for-All and opposes offensive arms shipments to Israel but affirms Israel's right to exist and defend itself [1, 4, 8, 9, 6]. DeGette had major backing from former Progressive Caucus Chair Pramila Jayapal, Pro-Choice Majority Action, and corporate PACs [4, 8, 6].

Kiros received endorsements from Senator Bernie Sanders, Democratic Socialists of America, Justice Democrats, and other progressive groups [1, 4, 8, 6]. She stated, "This isn’t just about replacing one generation of leaders with another. It’s about replacing it with moral clarity, with urgency, with courage — and making sure that the will of the voters is actually being represented and fought for at the federal level" [7].

Kiros declined to characterize a 2025 firebombing of pro-Israel demonstrators in Boulder as antisemitic, saying, "I don’t know what was in the heart of the perpetrator" and expressing uncertainty about the protesters' beliefs [1, 8, 9]. She also called the 9/11 attacks "inevitable" due to U.S. Middle East policy, remarks that generated controversy [1, 8, 9].

Kiros's victory is part of a broader national trend of democratic socialist and far-left candidates unseating establishment Democrats in 2026 primaries, including races in New York and Colorado [2, 3, 5, 7, 6].

Other Colorado Democratic primary results include Phil Weiser securing the Democratic gubernatorial nomination and Manny Rutinel winning a House primary [2, 3, 5].

Kiros is favored to win the general election in November in this heavily Democratic district. If elected, she would become the first Black woman and third woman overall to represent Colorado's 1st Congressional District [2, 3, 4, 5].
