Centrist House Democrats are alarmed after realizing that democratic socialists can beat them in primaries outside of New York City.On Tuesday, 29-year-old democratic socialist, lawyer, and Ethiopian immigrant Melat Kiros defeated 15-term incumbent Colorado Representative Dianna DeGette in a high-turnout election by an impressive ten-point margin, according to early results.DeGette is a longtime member of the Democratic establishment and was a member of the Congressional Progressive Caucus. But even with her progressive status, her support from dark money corporate super PACs and pro-Israel PACs, as well as her staunch support for Israel, made her particularly vulnerable to an attack from a candidate like Kiros—who was fired from her job over a social media post criticizing law firms’ support for Israel. Yet establishment Democrats still seem to be stunned by DeGette’s loss.“One more case in the growing dynamic of performative politics,” an anonymous House Democrat told Axios. “Diana was an excellent representative with seniority—but the style of someone younger and more outspoken has become more attractive to that cohort of motivated urban left voters.”BREAKING: Rep.

It’s literally their entire playbook.”But Kiros’s supporters point to the will of the voters, not a greater playbook.“If DeGette didn’t deserve a primary, Denverites wouldn’t have elected Melat by 10 points,” Justice Democrats spokesperson Usamah Andrabi told Axios. “All this outrage proves is the Democratic establishment’s contempt for their own voters.… It’s time for the party to catch up to its own base who are no longer interested in politicians who call themselves progressive but are bankrolled by corporate lobbies and AIPAC while voting to fund genocide and ICE.”Kiros’s victory comes on the heels of a clean sweep of Democratic Socialists of America victories in New York City, as Darializa Avila Chevalier defeated Representative Adriano Espaillat and Assemblymember Claire Valdez became the Democratic nominee in the 7th congressional district.“Denver voters of all ages, of all races, of all religions, sends a clear message: We will not wait,” Kiros said in her victory speech Tuesday night. “We will not wait to take the fight to Donald Trump and the oligarchy. We will not wait. We will not wait to abolish ICE and Medicare for all. We will not wait to put an end to the politics of the past, to get big money out of our politics, and to reject corporate packs at AIPAC. And no, we will not wait to end the genocide in Palestine. We believe that fundamental change can and will happen if we fight for it.”🎥 Recalling how she was fired from her law firm after refusing to remove a letter defending pro-Palestinian student protesters, Melat Kiros said, “I didn’t flinch because I stood by every word and I always will.”She added: “I know that will not be the only moment where those… pic.twitter.com/iI41zQp5wn— Drop Site (@DropSiteNews) July 1, 2026
