After a series of progressive primary victories in New York, democratic socialist candidates and organizers are trying to prove their momentum can reach far beyond New York City.
The Democratic Socialists of America and allied progressive groups are now looking to contests in Colorado, Michigan and Wisconsin as they attempt to turn local wins into a broader national strategy. The effort comes after several candidates backed by New York City Mayor Zohran Mamdani won Democratic primaries in New York, including Darializa Avila Chevalier and Claire Valdez, both aligned with the party’s left flank.
Those victories gave progressives a major confidence boost. They also intensified a growing debate inside the Democratic Party over whether candidates running on democratic socialist or strongly progressive platforms can win outside heavily blue urban districts.
The next major test is in Colorado’s 1st Congressional District, a solidly Democratic Denver-area seat represented for decades by Rep. Diana DeGette. She faces a primary challenge from Melat Kiros, a DSA-backed first-time candidate supported by progressive groups including Justice Democrats. The race has drawn national attention because it resembles the New York playbook: a younger left-wing challenger running against a long-serving Democratic incumbent in a safe blue district.
TRENDING TODAY
For progressives, the strategy is clear. They argue that many Democratic voters are frustrated with rising costs, housing pressure, healthcare expenses and what they see as a party establishment too slow to confront economic inequality. Mamdani has framed his movement as focused on affordability and working-class voters, saying Democrats must do more than simply oppose President Donald Trump.
That message has appeal in deep-blue districts where many voters are already comfortable with ambitious government programs, rent protections, public investment and criticism of corporate power. Supporters say the success of Mamdani-backed candidates shows that economic populism can energize younger voters, renters and left-leaning activists who feel ignored by traditional Democratic leadership.
Moderate Democrats see the situation differently. They warn that democratic socialist branding may help in places such as parts of New York City or Denver, but could hurt the party in swing districts where Republicans are eager to label all Democrats as extreme. They argue that winning safe blue primaries is not the same as building a national majority.
That concern is already shaping Republican messaging. GOP campaign officials have pointed to Mamdani and DSA-backed candidates as evidence that Democrats are moving left on crime, immigration, housing and foreign policy. Republicans are likely to use that argument heavily in competitive House races, especially in suburban and working-class districts that remain politically divided.
The results from other recent primaries show a more complicated picture. While DSA-aligned candidates scored major wins in New York, more establishment or center-left Democrats prevailed in several other races, including contests in Utah, Maryland, South Carolina and parts of New York outside the city’s most progressive districts. That suggests the Democratic Party is not moving in only one direction.
Still, the left’s victories matter because they show organized progressive groups can recruit candidates, build online attention, mobilize volunteers and defeat incumbents in low-turnout primaries. Even when those candidates run in safe Democratic seats, they can reshape the party’s internal agenda once elected.
For ordinary voters, the debate is not only about labels such as “socialist” or “moderate.” It is about whether Democrats can offer a believable response to the cost of living. Housing, groceries, healthcare, childcare and wages remain central issues for many families. Progressive candidates argue that bigger public action is needed. Moderates argue that Democrats must combine affordability policies with a message that does not alienate swing voters.
The next few races will help answer whether the New York model is portable. If Kiros or other DSA-backed candidates win outside New York, the argument for a national progressive wave will grow stronger. If they fall short, establishment Democrats will say Mamdani’s influence is powerful but limited to very blue political environments.
Some details remain uncertain, including whether DSA-backed candidates can win statewide primaries in battleground states such as Michigan or Wisconsin. Those races will be harder tests than safe congressional districts because they require broader coalitions and more general-election discipline.
For now, Mamdani’s movement has succeeded in forcing Democrats to confront a question they cannot avoid: is the party’s future built around centrist electability, left-wing economic populism, or some combination of both?
Why It Matters
The fight over DSA-backed candidates could shape the Democratic Party’s direction before the midterms. Progressives believe affordability and economic populism can build a new majority, while moderates worry that socialist labels will give Republicans powerful attack lines in competitive races.
What Comes Next
Colorado’s Democratic primary will be the next test of whether the New York progressive playbook can work in another city. After that, attention will shift to Michigan and Wisconsin, where left-wing candidates are testing whether democratic socialist energy can influence statewide races.
Kiros has campaigned on progressive economic policies, including Medicare for All and housing affordability, as DSA-backed candidates try to expand their influence beyond New York.
