Democratic congressional candidate Melat Kiros speaks to supporters at an election-night watch party on June 30, 2026 in Denver, Colorado.
Another Blow to Democratic Establishment as Melat Kiros Unseats 30-Year Incumbent in Colorado
“We won tonight, but this is also something so much bigger than this moment," said Kiros, a 29-year-old democratic socialist.
Melat Kiros, a 29-year-old democratic socialist and first-time candidate, defeated 15-term incumbent Rep. Diana DeGette on Tuesday in Colorado's 1st Congressional District primary, the latest signal that progressive momentum and backlash against the Democratic establishment are spreading nationwide.
"We won tonight, but this is also something so much bigger than this moment," Kiros, who was fired from the law firm Sidley Austin in 2023 for speaking out in support of Palestinian rights demonstrators, told backers late Tuesday after The Associated Press called the race in her favor. "We believe that fundamental change can, and will, happen if we fight for it—if we organize, if we show no fear in standing up for what’s right. That is the message that Denver has sent to both parties, to Donald Trump, and to the entire country."
Kiros' upset win came a week after a series of progressive victories in New York congressional primaries, which sparked backlash from the party's corporate wing. Days after the New York contests, more than a dozen centrist Democrats signed an open letter declaring that "we are capitalist, not socialist," a clear rebuke of insurgent progressives.
Justice Democrats, a national progressive group that backed Kiros, said it is having its "most successful cycle to date, winning six Democratic primaries and proceeding to the top two in two California primaries." The organization recruited Darializa Avila Chevalier, who upset five-term incumbent Rep. Adriano Espaillat in New York's 13th Congressional District last week.
"Melat and our candidates continue winning this cycle because Democratic voters are finally getting leaders acting on their demands to bring the fight to the corporations raising our prices, the war lobbies profiting off endless war and genocide, and the immigration gestapo terrorizing our communities," Alexandra Rojas, Justice Democrats' executive director, said in a statement Tuesday.
Kiros—whose platform includes Medicare for All, universal childcare, and abolishing Immigration and Customs Enforcement—prevailed despite a last-minute torrent of super PAC spending in support of DeGette. Drop Site reported that "super PACs funded by AIPAC and major big tech donors have poured roughly $2 million behind Rep. Diana DeGette on the eve of her contentious primary."
"Across the country, voters are rejecting corporate politics and electing candidates willing to take on billionaire influence, confront the climate crisis, fight for working people, and speak with moral clarity on the defining issues of the moment," said the youth-led Sunrise Movement following Kiros' win.
Kiros will be the heavy favorite to win the general election in November, when she will face Republican Christy Peterson.
Progressives also celebrated Colorado Attorney General Phil Weiser's Democratic gubernatorial primary win over US Sen. Michael Bennet, whose campaign received nearly $3 million in support from billionaire former New York City Mayor Michael Bloomberg.
“This movement is what democracy looks like,” Weiser told supporters late Tuesday. “You all sent a very clear message: The future of Colorado will not be decided by out-of-state billionaires, by corporations or special interests. Colorado’s future belongs to all of us."
An Urgent Message From Our Co-Founder
Dear Common Dreams reader, It’s been nearly 30 years since I co-founded Common Dreams with my late wife, Lina Newhouser. We had the radical notion that journalism should serve the public good, not corporate profits. It was clear to us from the outset what it would take to build such a project. No paid advertisements. No corporate sponsors. No millionaire publisher telling us what to think or do. Many people said we wouldn't last a year, but we proved those doubters wrong. Together with a tremendous team of journalists and dedicated staff, we built an independent media outlet free from the constraints of profits and corporate control. Our mission has always been simple: To inform. To inspire. To ignite change for the common good. Building Common Dreams was not easy. Our survival was never guaranteed. When you take on the most powerful forces—Wall Street greed, fossil fuel industry destruction, Big Tech lobbyists, and uber-rich oligarchs who have spent billions upon billions rigging the economy and democracy in their favor—the only bulwark you have is supporters who believe in your work. But here’s the urgent message from me today. It's never been this bad out there. And it's never been this hard to keep us going. At the very moment Common Dreams is most needed, the threats we face are intensifying. We need your support now more than ever. We don't accept corporate advertising and never will. We don't have a paywall because we don't think people should be blocked from critical news based on their ability to pay. Everything we do is funded by the donations of readers like you. When everyone does the little they can afford, we are strong. But if that support retreats or dries up, so do we. Will you donate now to make sure Common Dreams not only survives but thrives? —Craig Brown, Co-founder |
