The Democratic Socialists of America have rattled the political establishment this cycle by unseating several House incumbents in primaries. Now, the party is bracing for how these new members will behave once they arrive in Washington.
"We don't know how they will be part of the team," said Rep. Don Beyer (D-Va.). "We hope they'll be part of the team, but we don't know."
The question carries weight beyond the next Congress. With Democrats favored to take the House, the incoming socialist bloc could shape the party's legislative agenda and its public image heading into the 2028 presidential race, where Democrats aim to reclaim the White House after four years of Donald Trump.
The DSA-backed newcomers are vowing to push leaders on issues like "Medicare for All" and cutting U.S. aid to Israel. Some have already floated impeachment proceedings against Trump. They argue their own party has abandoned progressive principles and been too accommodating to the president's second term.
This creates a headache for House Minority Leader Hakeem Jeffries (D-N.Y.), who is poised to become Speaker if the House flips. He must balance the demands of the left with the needs of centrist members in swing districts who are vital to keeping the majority. The extent of the socialists' influence remains unclear, as does their willingness to force votes on their wish list.
Democratic anxiety is already surfacing. "The main question is: What is it like when we have these people here? Do they try to create problems?" said one House aide. "Do they say stuff that all our members get asked about? We're not super enthusiastic about that."
Democratic socialists are not new to Capitol Hill. Sen. Bernie Sanders (I-Vt.) and Rep. Alexandria Ocasio-Cortez (D-N.Y.) have long carried that banner. But the movement gained momentum after New York City Mayor Zohran Mamdani's victory last year, and his endorsements helped several DSA candidates win primaries this year.
The new members come from across the country: Donavan McKinney in Michigan defeated Rep. Shri Thanedar; Melat Kiros ousted Rep. Dianna DeGette in Colorado; and in New York, Darializa Avila Chevalier beat Rep. Adriano Espaillat, while Brad Lander, a former DSA member, took down Rep. Dan Goldman. Their common thread is a belief that congressional Democrats have not fought hard enough for core party values.
Within the DSA itself, there is debate over how aggressively to confront Jeffries. Some see the primary victories as a mandate to push hard, even if it means clashing with party leadership. "There's no time like the present," said one DSA member, speaking anonymously. "This is our year, and we've gotten the attention we need thus far. It would be foolish to let go once we actually get to Capitol Hill. Voters are asking for change."
Others urge caution. "I don't want DSA to become a party of no," said another member. "It does get you gains in the short term, but it's not a governing strategy."
Nomiki Konst, a progressive strategist and inactive DSA member, predicts most of the left will ultimately side with Jeffries. She points to Ocasio-Cortez's early struggles with then-Speaker Nancy Pelosi as a lesson. "You have a runway in the beginning and you should absolutely put some pressure on him to be on certain committees and push on popular issues like Medicare for All," she said.
The incoming socialists will test Jeffries' ability to manage a diverse caucus. He must deliver bold legislation to energize the base—expanding healthcare, strengthening environmental rules, and curbing Trump's deportation policies—while avoiding proposals that could hurt centrists in purple districts.
Former Rep. Steve Israel (D-N.Y.), who led the House Democrats' campaign arm, stressed the importance of unity. "The first priority for House Democrats when they get the majority will be to unify around a strategy to keep it," he said. "Building that unity won't be easy, but I think Hakeem Jeffries is made for this moment."
As the party navigates these dynamics, the 2028 primary landscape may also shift if Democrats win Senate seats in 2026, potentially reshaping the presidential field. Meanwhile, Trump's massive fundraising for the midterms adds another layer of pressure on Democrats to present a cohesive front.
