The Mamdani Sweep: DSA Captures Three House Seats as Anti-Israel Politics Wins NYC

Today’s lead: The Mamdani machine delivered — Lander defeats Goldman by 32 points, Chevalier and Valdez win, and a Palestinian-American DSA candidate who co-founded the anti-Israel ‘Not On Our Dime’ campaign wins a New York State Senate seat. The sweep is a structural shift in the Democratic Party’s relationship with Israel.

Also tracking: The US-Iran MoU is fraying on day one — Iran’s parliament speaker calls the deal ‘a declaration of America’s defeat’ as Vance and Rubio publicly contradict each other on Lebanon, and Israel’s ambassador warns the talks are a ‘train wreck.’ And the Montreal gunman’s 104-page manifesto is published — it explicitly targeted ‘influential Zionists’ and has been described as a fusion of far-left ideology and classical antisemitic conspiracy theory.

In the wire: UK’s BMA moves to investigate NHS use of the IHRA definition, the DOJ opens a civil rights probe into the Brooklyn cafe that refused service to Rep. Goldman over Israel support, and pro-Israel candidate Boafo wins the Maryland primary for Hoyer’s seat.

Ally signal. A unanimous 15-0 Assembly committee vote on a bill requiring California state agencies to collect and report data on Jewish identity — including in public schools — is a significant win. The bill, authored by Sen. Henry Stern and backed by a bipartisan author list including Sen. Ben Allen, now heads to Appropriations, where cost questions are typical but not historically decisive for data-collection measures. The lopsided margin signals little organized opposition at the committee level.

The Mamdani Sweep: DSA Captures Three House Seats as Anti-Israel Politics Wins NYC

SITUATION

New York City Mayor Zohran Mamdani’s candidates swept Tuesday’s congressional primaries — Brad Lander defeated incumbent Rep. Dan Goldman by 32 points in NY-10, Darializa Avila Chevalier (Columbia encampment alumna, refused to condemn Hamas) won NY-13, and Claire Valdez won NY-7. Palestinian-American DSA candidate Aber Kawas, co-founder of the ‘Not On Our Dime!’ campaign to end New York funding of organizations tied to Israel, won a State Senate seat. The night’s sole counter-narrative: pro-Israel candidate Adrian Boafo won the Maryland Democratic primary for Hoyer’s seat, backed by AIPAC and establishment Democrats.

KEY DEVELOPMENTS
  • Lander 66%, Goldman 34% — with 89% of votes counted, the margin was not close; Goldman told reporters Israel played an ‘outsized role’ in the race.
  • Avila Chevalier refused to affirm Israel’s right to exist when directly asked during the campaign; she wore a keffiyeh throughout and called Israeli actions ‘genocide.’
  • Aber Kawas co-launched ‘Not On Our Dime,’ a campaign to tax New York-registered organizations that donate to Israel or Israeli charities — a direct BDS-aligned financial pressure campaign.
  • Jewish Democrat Micah Lasher won NY-12 (Nadler’s open seat) over Jack Schlossberg and others, backed by Hochul and Bloomberg — the one Manhattan race that did not go to the DSA.
  • Israel emerged as a ‘central point of debate’ in the primaries, with JDCA-backed candidates defeated in NY-10 and NY-13.
WHY THIS MATTERS

The DSA's anti-Israel platform won three House seats in the world's largest Diaspora Jewish community — that result confirms Mamdani's personal win was a movement, not an anomaly. The Democratic Party's emerging left flank now has concrete congressional power, and the 2026 midterms will stress-test whether this coalition can replicate outside New York City's ideological monoculture or whether the map limits its national reach.

Iran Calls US Deal 'America's Defeat' as Vance-Rubio Split Deepens and Lebanon Talks Hit 'Train Wreck'

SITUATION

The US-Iran Memorandum of Understanding is unraveling on day one: Iran’s parliament speaker called it ‘a declaration of America’s defeat,’ while Vice President Vance and Secretary Rubio publicly contradicted each other on whether Iran would have a role in Lebanon. Israeli Ambassador Yechiel Leiter warned that Washington talks are becoming a ‘train wreck’ after a US-Iran deconfliction cell was agreed to for Lebanon without Israel’s participation. IAEA chief Grossi confirmed inspections of bombed nuclear sites ‘are going to happen’ — but Tehran denied agreeing to the terms Trump announced, and Iran’s FM simultaneously called Hamas to discuss the deal.

KEY DEVELOPMENTS
  • Iran’s parliament speaker told an OIC meeting that the deal shows Washington ‘retreated both on the battlefield and at the negotiating table.’
  • Vance says Iran agreed to IAEA inspections ‘into infinity’; Iran’s Foreign Ministry said bombed nuclear sites were not scheduled for inspection and ‘never will be.’
  • Senate passed a war powers resolution 50-48 directing Trump to halt Iran military action — largely symbolic but a political rebuke; Trump called it ‘aid and comfort to the enemy.’
  • The Trump administration is planning an $80 billion supplemental funding request to Congress to replenish war stockpiles.
  • Israel’s Lebanon position: Katz said Israel will not withdraw from southern Lebanon even under US demands, as new Washington talks open on a US-backed plan to hand territory to the Lebanese army.
WHY THIS MATTERS

The Vance-Rubio messaging split on Lebanon is not a communications failure — it reflects a genuine White House policy fracture over whether Iran gets a role in the post-war Levant architecture. Israel's public 'train wreck' warning is unusually direct; it signals Jerusalem has assessed that the deconfliction mechanism, if implemented, locks in an Iranian veto over Lebanese security arrangements regardless of what the formal ceasefire text says.

Montreal Gunman's 104-Page Manifesto: 'Influential Zionists' Were the Target

SITUATION

The manifesto left by the gunman who killed a rabbi and a police officer in Cote-des-Neiges has been published, revealing a 104-page document fusing far-left ideology, antisemitic conspiracy theory, and incel grievances. The killer explicitly identified ‘influential Zionists’ as targets, described ‘the Judaeo-bourgeois class’ as controlling Western institutions, and drove several hours to reach Montreal’s heavily Jewish neighborhood. Quebec authorities identified the suspect as 24-year-old Evan Hatfield.

KEY DEVELOPMENTS
  • The manifesto describes Jews and Zionists as wielding improper influence over finance, politics, media, and Western institutions — classical conspiracy-theory antisemitism.
  • Hatfield drove from outside the city to reach Cote-des-Neiges, one of Montreal’s most densely Jewish neighborhoods, indicating deliberate target selection.
  • The document was sent to multiple media outlets before the attack, classifying this as ideologically premeditated antisemitic terrorism.
  • A Jewish civilian, a police officer, and the suspect were killed; a second officer was seriously injured.
WHY THIS MATTERS

The manifesto confirms the Montreal attack was ideologically targeted antisemitic terrorism, not a random shooting. The fusion of far-left anti-Zionist framing with classical Jew-hatred in a single perpetrator's worldview is a documented radicalization pathway — and the 'influential Zionists' language mirrors rhetoric circulating in mainstream progressive political spaces in the US.

One Win in Primary Night: Boafo Beats Crowded Field for Hoyer's Maryland Seat

SITUATION

Maryland state Delegate Adrian Boafo won the Democratic primary in MD-5 to succeed retiring Rep. Steny Hoyer, securing 32% in a 24-candidate field. Boafo was backed by Hoyer, AIPAC, and pro-Israel Democrats — a clean win for the establishment in a night that otherwise delivered losses for pro-Israel candidates in New York. He is a strong favorite in November in the safely Democratic district.

KEY DEVELOPMENTS
  • Boafo secured 32% with runner-up Quincy Bareebe at 19% — a comfortable margin in a crowded field.
  • AIPAC invested in Boafo, making the win a direct counterpoint to the New York sweep — pro-Israel candidates can still win Democratic primaries with the right coalition.
  • The district — MD-5 in Prince George’s County and southern Maryland — is safely Democratic, making Boafo the presumptive next congressman.
WHY THIS MATTERS

Boafo's win keeps Steny Hoyer's legacy seat in pro-Israel Democratic hands and demonstrates the Maryland coalition-building model still works — AIPAC investment, establishment Democratic backing, and a candidate with deep district ties. The contrast with New York is instructive: Hoyer's successor was chosen in a multi-candidate field where AIPAC had maximum impact; Goldman's loss was in a two-person race where the Israel issue was impossible to dilute.
