As the Democratic Party lurches left in the run-up to the midterms — and amid the rise of high-profile, far-left Senate candidates such as Graham Platner in Maine and Abdul El-Sayed in Michigan — candidates affiliated with the Democratic Socialists of America (DSA) have gradually been making inroads and positioning themselves to win nominations in several key House races. 

This has happened without much protest or opposition from Democratic Party leadership. And given that the urban districts where the DSA-endorsed candidates have the most support are so heavily Democratic, there hasn’t been much incentive for party groups to set red lines against radicals looking to disrupt the party in these lower-profile races. 

One of the most insidious aspects of the advocacy of many DSA chapters is the demand that its endorsees cut ties with any Jewish group that recognizes the State of Israel. Some chapters celebrated or justified Hamas’ Oct. 7 terror attacks against Israel. 

“They are trying to do in America what [the Boycott, Divestment and Sanctions movement] seems to do internationally, which is to make being Jewish unacceptable in polite society,” Ron Halber, the CEO of the Jewish Community Relations Council of Greater Washington, recently said on a webinar of D.C-area Jewish leaders. 

But despite the group’s radical views, DSA-endorsed candidates have a real shot at prevailing in several upcoming Democratic primaries in major cities. 

Pennsylvania state Rep. Chris Rabb, one of several Democrats looking to succeed retiring Rep. Dwight Evans (D-PA) in his Philadelphia district, has the notoriety of recirculating an Instagram post blaming the Bondi Beach terrorist attack that killed 14 Jewish Australians on “Zionists,” insinuating the terror attack was a false flag. (His campaign later blamed a former staffer for reposting the item.)

Rabb, who has been endorsed by many of the leading anti-Israel progressives in Congress, also recently campaigned with antisemitic streamer Hasan Piker. His far-left views and virulent criticism of Israel has alarmed Gov. Josh Shapiro, according to Axios, and the popular Pennsylvania governor has worked behind the scenes to oppose his campaign. 

Democratic sources familiar with the primary, however, suggest that any behind-the-scenes efforts aren’t having much effect in derailing the DSA candidate’s campaign. Rabb’s two leading opponents — surgeon Ala Stanford and state Sen. Sharif Street — are both mainstream Democrats and may potentially split the more-moderate vote. The primary is on Tuesday.

Next month, a similar clash between the Democratic mainstream and socialist wing of the party is taking place in New York City, where state Assemblymember Claire Valdez, who is backed by Mayor Zohran Mamdani and New York’s DSA chapter, is squaring off against Brooklyn Borough President Antonio Reynoso, the progressive establishment’s favorite. 

The race, in one of the most left-wing districts in the city, which covers part of Brooklyn and Queens, will mark a major test of Mamdani’s political capital — and whether the DSA brand is more compelling to progressives than the endorsement of Reynoso by retiring liberal stalwart Rep. Nydia Velazquez (D-NY).

Reynoso, in an interview with The New York Editorial Board, proclaimed himself the underdog in the race despite boasting endorsements from organized labor, the outgoing congresswoman, state Attorney General Letitia James and the left-wing Working Families Party line. “Zohran Mamdani is a celebrity-status, inspiring figure at the levels of AOC and Bernie Sanders. He is a movement and is deeply important,” Reynoso said.

Meanwhile, in Denver, another DSA hotbed, Rep. Diane DeGette (D-CO) faces a primary threat from DSA-backed challenger Melat Kiros, a 28-year-old attorney. Kiros has made criticism of Israel a centerpiece of her campaign, accusing Israel of genocide, and she supports an arms embargo against the Jewish state. Kiros dominated DeGette at a districtwide party convention filled with activists in March, and the congresswoman has been airing ads touting her progressive record, in anticipation of a competitive June primary.

And in St. Louis, the local DSA chapter is again backing former Rep. Cori Bush (D-MO), who was one of the most extreme anti-Israel lawmakers when serving in Congress, in her attempt at a comeback against Rep. Wesley Bell (D-MO).

(The other major contest featuring a DSA-endorsed contender is next month’s D.C. mayoral primary, where Jewish groups have been alarmed by Janeese Lewis George’s rhetoric around Israel and antisemitism.)

All told, there could be at least four Democratic Socialists of America-endorsed lawmakers in the next Congress, with limited party efforts to marginalize the extremists from within. It underscores how fast the Democratic Party is evolving, and how quickly the guardrails that kept the party centered — and largely free of antisemitism — are falling out of place.
