Socialists and progressives topple Denver Democrat

In Denver’s Colorado 1st Congressional District, voters chose democratic socialist attorney Melat Kiros over longtime Rep. Diana DeGette, delivering another punch to Democratic incumbents as anti-establishment anger fuels progressive and socialist wins nationw

On Tuesday in Denver, the anti-establishment mood didn’t just show up at the polls—it turned the page.

Voters chose democratic socialist Melat Kiros. an attorney who lost her job for condemning her industry’s silence on Israel’s genocide in Gaza. over longtime Rep. Diana DeGette in Colorado’s 1st Congressional District. DeGette, a Democrat who has represented Denver for decades, touted progressive positions on domestic issues. But she faced mounting criticism that she had grown complacent over three decades in Congress and generally followed the party line on support for Israel.

DeGette’s defeat landed as Democratic incumbents across the country reel from losses in New York last week and face what party leaders describe as proof that some challengers’ visions are out of step with the base. But leftists and progressives kept winning anyway—turning the battle over the Democratic Party’s future into something decided at the ballot box.

“In the last week, we have taken out 40 years of incumbency,” said Usamah Andrabi, spokesperson for Justice Democrats, which backed Kiros and two of the candidates who won in New York.

Andrabi framed the message as one about money and access—saying Democratic establishment figures “hate that they can no longer simply spend unlimited sums of money to buy a seat in Congress. ” and that organized “people power and mass movements can beat the money.” He added. “We’re just having an amazing fucking cycle.”.

Kiros will now face Republican Christy Peterson in November, with strong expectations that she will win in the solid Democratic district.

The same anti-incumbent sentiment surfaced in Colorado’s governor race. where state Attorney General Phil Weiser—despite holding statewide office—cast himself as the outsider against the establishment. Two-term Weiser defeated sitting Sen. Michael Bennet after portraying himself as having gone after President Donald Trump in court dozens of times and won—an approach that closely tracks a common playbook for Democratic state attorneys general.

Not every contest in Colorado followed that pattern, though. In the statewide Senate race, incumbent Sen. John Hickenlooper safely kept his seat while progressive challenger Julie Gonzales fell short. Hickenlooper refused to debate Gonzales and tried to thwart her run early in the race.

Beyond Denver, the results across key districts showed a patchwork—some victories for the anti-establishment wave, other signs that the Democratic establishment’s grip still has limits.

In Colorado’s 5th Congressional District. the race for an open seat in the Colorado Springs area went to Jessica Killin. an Army veteran and previous chief of staff to Doug Emhoff’s former second husband. who beat Joe Reagan. a populist second-time candidate and fellow veteran. The campaign finance gap was central: Killin far outraised him, aided by backing from the Democratic Congressional Campaign Committee.

Days before the 5th District primary. Killin pledged she would sign onto a new pact from conservative House Democrats to promote capitalism—equating socialism with the right-wing MAGA movement—and promised to fight both. She will face first-term GOP Rep. Jeff Crank. The Cook Political Report changed Crank’s district from “solid” to “likely” Republican.

In the 8th Congressional District, State Rep. Manny Rutinel. described as progressive but accused of reneging on some policy pledges. won against a former state lawmaker backed by conservative Democrats’ Blue Dog PAC. The 8th District race had been rated a “toss up. ” and it was listed among the DCCC’s “races in play” that could shape control of the House. Rutinel will face freshman GOP Rep. Gabe Evans, ranked last summer as the most vulnerable incumbent in the country.

Rutinel’s campaign emphasized immigration. In a heavily Latino district, he said he was running to fight the “cruelty” of Trump’s immigration policy and attacked his opponent, Shannon Bird. He positioned himself as the candidate who would do more to rein in Immigration and Customs Enforcement.

Rutinel, backed by the campaign arm of the Congressional Hispanic Caucus, also moved away from some of his more left-leaning stances during the campaign. He backed off Medicare for All and opposing fracking. He ran without the support of the Working Families Party, which previously endorsed him.

For all that, his stance on Israel remained a flashpoint. While Rutinel had reportedly been privately critical of Israel’s genocide in Gaza, he told voters he wouldn’t “boil it down to one word descriptors” and said he would support military aid to Israel.

Bird, meanwhile, carried institutional support from the centrist and party-aligned New Democrat Coalition Action Fund and EMILY’s List. She also had support from the pro-Israel Democratic Majority for Israel PAC. and while Rutinel had an advantage in fundraising and dominated ad space. House Majority PAC—which aligns with House Democratic leadership—had already reserved $6.1 million in ad reservations for the general election.

Carlos Valverde. Southwest regional director for the Working Families Party. offered a blunt contrast between what he called corporate influence and working-class priorities. “Voters can see through the hollow words and platitudes of the corporate-backed candidates who have tried to hijack our working families-centered messaging during this campaign. ” Valverde said. pointing to frustration over housing. healthcare. wages. and what he described as “basic dignity.” He said people were tired of “status-quo. do-nothing politics that protect the comfortable while working families struggle.”.

In Denver, Andrabi said the Kiros campaign benefited from something that can’t be summed up on a ballot line: supporter energy on the ground.

He said DeGette received a last-minute infusion of super PAC money, but that the Kiros campaign “knocked 115,000 doors in this race, which is just insane.”
