New Jersey/New York anti-establishment earthquake rocked Colorado Tuesday

The political ground shifted again Tuesday night.

Just one week after a slate of insurgent candidates toppled establishment figures in New York City, Colorado voters delivered their own verdict on the Democratic establishment. The message was unmistakable: loyalty to the party machine no longer guarantees survival.

Melat Kiros, a 29-year-old democratic socialist and former attorney who was fired from her job for defending pro-Palestinian law students, defeated 15-term Rep. Diana DeGette in the Democratic primary for Colorado’s 1st Congressional District. With more than 90 percent of precincts reporting, Kiros led 51 percent to 42 percent, a margin that stunned even her most optimistic supporters.

“I lost my job for speaking out,” Kiros said in her victory speech Tuesday night. “Now I’m going to Congress.”

DeGette, first elected in 1996 — three years before Kiros was born — had never faced a serious primary challenge. She entered the race with the advantages of incumbency, seniority and a fundraising operation that dwarfed her opponent’s. But those advantages proved insufficient against an electorate hungry for what Kiros called “fighters, not fundraisers.”

“For decades Democrats have failed to meaningfully deliver for working families,” Kiros said in an interview after the race was called. “We have to root out the corruption and get money out of our politics. It’s not about popular support, it’s about political will — and that means we have to vote out any incumbents that are standing in our way by taking that kind of corporate PAC money.”

She added that her victory meant she would not support House Minority Leader Hakeem Jeffries for speaker.

The anti-establishment wave did not stop with Kiros.

Colorado Attorney General Phil Weiser, 58, defeated three-term Sen. Michael Bennet, who had held the seat since 2009. Weiser, who has served as the state’s top law enforcement officer for two terms, built his campaign around the dozens of lawsuits he has filed against President Donald Trump’s administration, including challenges to the president’s executive orders on birthright citizenship and federal funding freezes.

“I’ll always stand up to bullies, especially Donald Trump,” Weiser said in an ad earlier this year. “Congress isn’t doing it. But I am.”

Weiser’s victory was narrower than Kiros’ but no less significant. He defeated Bennet by a margin that will send shockwaves through the Democratic establishment, which had counted on Bennet’s seniority and fundraising prowess to hold the seat.

Bennet had outspent Weiser significantly, but the message that resonated with voters was Weiser’s: that the state’s senior senator had grown too comfortable in Washington and had lost touch with the urgency Colorado voters feel.

In the state’s other Senate contest, Sen. John Hickenlooper defeated state Sen. Julie Gonzales, a democratic socialist-aligned candidate, by a single-digit margin. Hickenlooper, a former governor and Denver mayor, entered the race with a nearly 9-to-1 fundraising advantage over Gonzales. Yet she led him in Denver, the city where he once served as mayor.

The closeness of the race stunned political observers who had written off Gonzales as a longshot.

“Mamdani’s sweep in New York was a political earthquake,” said Joseph Geevarghese, executive director of the progressive political group Our Revolution. “Colorado is the aftershock. This is not an accident, and it is not isolated to New York. The same energy that elected Zohran Mamdani as mayor just elected an entire slate behind him.”

The New York results Geevarghese referenced were nothing short of revolutionary. Mayor Zohran Mamdani, who defeated former Gov. Andrew Cuomo in last year’s mayoral race, saw all three of his endorsed congressional candidates win their primaries last week.

Activist Darializa Avila Chevalier ousted Rep. Adriano Espaillat. Former New York City Comptroller Brad Lander defeated Rep. Dan Goldman. And state Assembly Member Claire Valdez won the open seat vacated by retiring Rep. Nydia Velazquez.

All three candidates have ties to the Democratic Socialists of America and campaigned on platforms including Medicare for All and ending U.S. military support for Israel’s operations in Gaza.

“The people of New York City and throughout this country are sick and tired of a rigged economic system in which the rich get richer and working families are struggling to put food on the table,” said Sen. Bernie Sanders, the Vermont independent and democratic socialist who endorsed Kiros. “People are tired of a corrupt campaign finance system in which billionaires through their super PACs are trying to undermine democracy and buy elections.”

Garden State moderates are feeling uneasy as progressive candidates like Analilia Mejia and Adam Hamawy are stirring things up and redefining what it means to be a Democrat in New Jersey.

America’s most vulnerable Republican incumbent—Rep. Tom Kean Jr. has been absent for four months—will defend his seat in November’s general election against Texas Republican Rebecca Bennett, a former Navy helicopter pilot who won the Democratic nomination by raising far more money than three moderate challengers who were vying to take his 7th Congressional District seat.

Kean probably lost his election by siding with President Donald Trump’s brutal immigration enforcement and $1 trillion Medicaid cut that was used to provide billionaire tax breaks, long before he suffered a nervous breakdown.

It doesn’t help that the GOP lawmaker checked into a hospital for treatment at taxpayer expense shortly after cutting care for millions of America’s poorest working families. Since the One Big, Beautiful Bill Act (OBBBA) became law one year ago, over 3.8 million people have already lost Medicaid or CHIP coverage.

In Colorado’s most competitive House district, state Rep. Manny Rutinel cruised to the Democratic nomination to face Rep. Gabe Evans, a Republican. Rutinel, who was backed by prominent Latino groups and a wave of progressive support, focused his campaign on attacking Evans for failing to stand up to the Trump administration’s immigration enforcement operations.

“Folks right now are upset with the establishment, and they’re looking for fighters who are going to stand up to Donald Trump and Gabe Evans, because they are destroying our economy,” Rutinel said. “We need fighters who understand the struggles, and we’ll fight for them every single day. That’s what I’ve done throughout my entire career. That’s what I’m going to do when I’m in Congress.”

The Colorado results follow a pattern that has emerged across the country this primary season. Progressive candidates have won in Washington, D.C.’s mayoral race, in congressional contests in New Jersey and Pennsylvania, and in battleground House districts from Maine to California.

“Every single thing that you care about, from social justice to economic justice to environmental justice, all of these things are intertwined with who has the money and the influence to wield power over our government,” Kiros said in an interview earlier this month.

Kiros’ path to victory began with a termination. Two years ago, while working as an attorney in New York, she wrote an open letter defending law students who had organized for Palestine. Her employer asked her to take it down. She refused, was fired and moved back to Colorado within a week.

She took a job as a barista to make ends meet and launched her congressional campaign on a platform that includes Medicare for All, universal childcare, artificial intelligence regulation, abolition of U.S. Immigration and Customs Enforcement and an arms embargo on Israel.

Justice Democrats, the progressive group that endorsed Kiros in December, framed her victory as validation of their strategy.

“Our candidates are winning because they are running on an affirmative vision to make life more affordable for working class voters — from Medicare for All to ending taxpayer-funded genocide — and they are not afraid to call out a Democratic establishment that stopped fighting for us the minute they started being bankrolled by the corporations raising our prices,” said Usamah Andrabi, a spokesperson for the group.

Kiros was also backed by the Democratic Socialists of America, which ran phone banks for her campaign nearly daily in the final stretch, knocking on more than 100,000 doors and making more than 500,000 calls in Denver.

Popular streamer Hasan Piker, who emerged as a visible outside organizer in New York’s insurgent sweep, dedicated multiple streams to boosting Kiros’ candidacy. He hosted her for an extended interview and ran marathon phone-banking sessions for her campaign live on his stream before traveling to Denver to campaign with her in person on primary day.

“A thirty-year incumbent was defeated tonight,” Piker said. “It’s clear that there is a real hunger for change. Democrats all over the country are demanding it. That change is a working class centered movement. It’s socialism. We are not done yet.”

The results have already begun to reshape conversations about the future of the Democratic Party. The success of candidates backed by the Democratic Socialists of America and aligned with Mamdani’s movement has raised questions about the party’s leadership, particularly Sen. Chuck Schumer of New York.

A Siena University poll released in May found Schumer had a 33 percent approval rating among all voters and a 47 percent approval rating among Democrats. The frustration with Schumer, combined with the resounding success of democratic socialist candidates in New York and Colorado, has fueled speculation about a primary challenge to the Senate minority leader.

Rep. Alexandria Ocasio-Cortez has been floated as a potential challenger to Schumer in 2028. The New York Democrat is one of the most visible faces of the party and a prolific fundraiser. Her “Fighting Oligarchy” tour with Sanders last year drew large crowds at a time when the Democratic Party appeared stuck in a rut.

When asked about the possibility of a progressive challenge, a Schumer spokesperson pointed to the senator’s remarks from Wednesday.

“We’re seeing tremendous energy from all different areas of our party,” Schumer said. “You’re seeing centrist energy in Virginia, Iowa and New Jersey. Progressive energy in New York City. We’re going to harness it all to win in November. Because all Democrats are united in the mission of taking back the Senate and defeating Trump.”

But progressives see the results differently.

“New York’s clean sweep was a political earthquake that shows voters want shake-up-the-system fighters who are not owned by corporate interests, billionaires or corrupt Trump allies like AIPAC,” said Adam Green, co-founder of the Progressive Change Campaign Committee. “This is obviously bad news for Chuck Schumer — who is the exact wrong image for Democrats if the party wants to win.”

Lupe Todd-Medina, a Brooklyn-based political strategist who formerly worked for Jeffries, said among Democrats she hears from, there is no doubt Schumer will face a primary challenge if he runs in 2028.

“Ocasio-Cortez’s name was already on the tongues of Democratic voters for some time, but it also is being talked about in the sense of, is Senator Schumer going to retire, and if he doesn’t retire, the name that comes up who will challenge him has been Congresswoman Ocasio-Cortez,” Todd-Medina said. “I actually have not heard another name.”

Kiros said she intends to work with the new wave of progressive candidates to push the Democratic Party leftward.

“If enough of us share that commitment to Medicare for All, to ending corporate capture, to an arms embargo on Israel, we should absolutely say: here are our conditions,” she told Axios. “If you want our votes on leadership, on appropriations, this is what it costs.”

The question now is whether the energy that swept Kiros, Weiser and the New York slate into nomination can be sustained through November.

Republicans have already begun to frame the results as proof that Democrats are embracing socialism. Rep. Lauren Boebert, a Colorado Republican, called the results evidence that Democrats “are showing their true colors and saying we want socialism, inevitably we want communism.”

But Kiros and her allies reject that framing. They argue their victories are not about ideology but about results — about voters who are tired of a system they believe has failed them.

“Voters are angry,” said Doug Friednash, a longtime Colorado Democratic strategist and former chief of staff to Hickenlooper. “They are all anti-establishment and don’t feel like our leaders have fought hard enough and don’t have a coherent voice. Kiros is the clincher.”

The results in Colorado and New York suggest that anger is not limited to one city or one state. It has become a national phenomenon.

“Every single thing that you care about, from social justice to economic justice to environmental justice, all of these things are intertwined with who has the money and the influence to wield power over our government,” Kiros said.

“Coloradans need a governor who is a fighter,” Weiser said in his ad. “I’ll always stand up to bullies, especially Donald Trump. Congress isn’t doing it. But I am. We are stopping him in court, winning 34 times and counting.”
