The Democratic Socialists of America spent last week knocking off two sitting Democratic members of Congress in New York City. They posted their victory lap on social media before the ballots were even fully counted. "Today, the East Coast, next week the Mountain West." These people are not messing around.
What Just Happened in New York
Here's the thing about last week's primaries that the mainstream political press is still struggling to process: this wasn't a fluke. Darializa Avila Chevalier, a 32-year-old community organizer with DSA backing, knocked out Adriano Espaillat, the sitting chair of the Congressional Hispanic Caucus, a man with serious institutional clout and establishment money behind him. That's not a protest vote. That's a scalp.
Then Claire Valdez, another DSA-aligned candidate, won her own congressional primary on the same night. Two incumbents or establishment picks, one evening, same playbook. Fox News reports that both candidates had the active support of New York City Mayor Zohran Mamdani, whose own stunning mayoral win a year ago first announced the DSA as a genuine power broker in Democratic politics rather than a fringe Twitter phenomenon.
Mamdani, for his part, is already thinking bigger. After watching his endorsed candidates sweep, he told supporters, "My goal is to make America a place that every American can afford." That's a national message, delivered by a guy who just proved his endorsement is worth something.
Colorado Is Already in the Crosshairs
The ink wasn't dry on the New York results before the DSA pivoted west. According to Fox News, the group is backing Melat Kiros in Tuesday's Democratic primary in Colorado's 1st Congressional District, a Denver-anchored seat that Kamala Harris carried by 56 points in 2024. The opponent is Diana DeGette, who has held the seat for thirty years.
Kiros is a first-time candidate and former attorney who was born four months after DeGette first won the seat. She also has Justice Democrats in her corner, the group that helped launch Alexandria Ocasio-Cortez, Ilhan Omar, Rashida Tlaib, and Ayanna Pressley into Congress by doing exactly what the DSA is doing now: targeting safe blue seats where an energized primary challenger can beat a complacent incumbent without ever having to worry about a general election.
The DSA's social media pitch for the race is about as subtle as a brick through a window: "ELECT ANOTHER SOCIALIST TO CONGRESS ON JUNE 30TH." No dog whistles here. Full bark.
Michigan and Wisconsin Come Next
Beyond Colorado, Fox News reports the DSA has bigger targets on the August calendar. In Michigan, Abdul El-Sayed is running for the Senate seat being vacated by retiring Democrat Gary Peters. El-Sayed is DSA-aligned, backed by Bernie Sanders, and a former Wayne County health director who ran for governor back in 2018 and lost. He's one of three major candidates in what is shaping up to be a real fight for a seat in a genuine battleground state.
In Wisconsin, state Rep. Francesca Hong is mounting a run for governor in the race to succeed retiring Gov. Tony Evers. Hong posted on social media last week, "It's a great day to be a democratic socialist. Wisconsin is next!" Both of these races matter in ways that the New York primaries, happening in some of the bluest zip codes on the planet, do not. Michigan and Wisconsin are states that actually swing. Winning there would mean something different entirely.
Why It's Working, and Why That's Complicated
Democratic strategist Joe Caiazzo, a veteran of both Bernie Sanders presidential campaigns, told Fox News Digital that the DSA and the broader left wing of the party are "the only ones truly engaging in a conversation about economic populism in a period where costs continue to soar, and there is seemingly no plan from anyone in Washington to rectify that problem." That's a pretty honest assessment from someone who would know.
Even the opposition agrees the movement has momentum. Matt Bennett of Third Way, a centrist Democratic outfit, acknowledged to Fox News that there is "enormous energy around the far left in very, very blue places" and that they are "succeeding in their mission to oust incumbents or mainstream Democrats from blue seats and make them bluer." That framing, making blue seats bluer, is exactly what centrists are worried about. A socialist representing Brooklyn is a very different political animal than a socialist representing Macomb County.
And the results are not uniformly pointing left. In Manhattan, the race to succeed longtime Rep. Jerry Nadler went to Micah Lasher, a former Nadler staffer and establishment pick. Up in New York's 17th District, a genuine swing seat, Army veteran Cait Conley won the Democratic primary and will face Republican Rep. Mike Lawler in a race that could determine whether Republicans hold the House. The far left didn't touch that one.
The Part Everyone Is Tiptoeing Around
The DSA is running a coherent, disciplined national strategy. They identify blue seats where low-turnout primaries give an organized, energized minority serious leverage. They build coalitions with aligned groups like Justice Democrats. They find candidates who fit the moment, young, ideologically clear, willing to run hard on economic populism. And they get a high-profile endorser, in this case a sitting big-city mayor, to give the whole operation credibility and media oxygen.
This is not spontaneous. This is infrastructure. The question the Democratic establishment has not yet answered, and appears to be fumbling toward answering badly, is what they actually offer voters who are furious about costs, housing, healthcare, and wages. "We're not socialists" is not a message. It's a dodge.
The Dingo Take
Here is a thing that is true: the Democratic Party establishment has spent the last several years watching its working-class coalition erode on one side to MAGA economic populism, while getting outflanked on the other side by a socialist movement that is at least showing up with an actual answer to the question of why rent costs more than your parents' mortgage. You can disagree with the DSA's answers. You can think democratic socialism is the wrong direction for the country. But you cannot look at what happened in New York last week and pretend the establishment is winning the argument.
The centrist response so far has been variations of "this will hurt us in swing districts" and warnings about electability, which might carry more weight if the establishment wing had a compelling economic message ready to go. They don't. Joe Caiazzo, who worked for Bernie Sanders twice and is presumably not a neutral observer here, told Fox News the left is the only faction actually talking about the cost of living. When your own critics are saying that, you have a problem that is not solved by pointing at a polling crosstab.
Watch Colorado tonight. Watch Michigan and Wisconsin in August. The DSA said "today the East Coast, next week the Mountain West" and they weren't joking. Whether you think that's exciting or terrifying probably depends on what you think the Democratic Party is actually for. That fight, the one over what the party is fundamentally for, is the only primary that actually matters right now.
