Democratic socialists are poised to expand their presence in the U.S. House of Representatives following the 2026 midterm primaries, with several newcomers securing victories in key Democratic strongholds. These candidates, who identify with the far-left wing of the party and the Democratic Socialists of America (DSA), have overturned longtime incumbents and are expected to reinforce the progressive faction in Congress.
Among the successful candidates is Darializa Avila Chevalier of New York, who defeated veteran Representative Adriano Espaillat in a district covering parts of upper Manhattan and the Bronx. A former community organizer and campaign staffer for New York Mayor Zohran Mamdani, Chevalier embraced a platform focused on uplifting working-class voters and challenging the influence of corporate donors. Her campaign also prominently featured opposition to Israeli policies in Gaza, reflecting her activism, including a recent arrest during a protest against Israeli Prime Minister Benjamin Netanyahu’s United Nations speech.
In Colorado, Melat Kiros, a 29-year-old immigrant from Ethiopia, unseated 30-year incumbent Diana DeGette in the Denver area. Kiros, a lawyer turned doctoral student, positioned her campaign around bold progressive initiatives such as abolishing U.S. Immigration and Customs Enforcement, implementing Medicare for All, and opposing the Israeli government’s actions in Palestine. Kiros described her campaign as part of a broader movement aimed at confronting entrenched political and economic powers.
Michigan’s Donavan McKinney, a state legislator, overcame a significant funding gap to defeat Representative Shri Thanedar in a Detroit district. McKinney’s grassroots campaign emphasized utility reform, campaign finance changes, and Medicare for All, asserting that the Democratic Party must choose between serving working people or the corporate elite. He holds formal endorsement from the DSA.
In Pennsylvania, Chris Rabb, a Philadelphia state representative with a decade of legislative experience, won a four-way primary in a predominantly Democratic district. A member of the Philadelphia DSA chapter since 2026, Rabb campaigned on issues including campaign finance reform, abolishing ICE, addressing food deserts through government-operated grocery stores, and expanding the federal minimum wage to cover gig economy workers. He highlighted a disconnect within the Democratic Party between its financial backers and everyday voters.
Claire Valdez, a New York state legislator and part of Mamdani’s progressive slate, secured a Democratic primary victory in a gentrifying Brooklyn and Queens district. Valdez, associated with the New York City DSA since 2019, campaigned on affordability, generational change, and strong opposition to former President Donald Trump, aiming to sustain the momentum of the recent populist shift within the party.
Other left-leaning candidates, some outside the DSA, also garnered attention. Adam Hamawy, an army veteran and medical doctor, is running in a safe New Jersey district and supports anti–corporate money reforms despite not being a DSA member. In California, Angela Gonzales-Torres is challenging Representative Jimmy Gomez, while in Michigan, former DSA member William Lawrence is contending for a competitive seat held by Republican Tom Barrett.
While Republicans have highlighted socialism as a warning in their midterm messaging, the growing influence of democratic socialists within the Democratic Party indicates shifting dynamics. This emerging cohort of progressive lawmakers is expected to shape legislative priorities and party direction as the 2026 election’s outcomes solidify.
