The political action arm of a Jewish anti-Zionist group best known for staging sit-ins to protest genocide in the halls of power is endorsing its first-ever candidate for U.S. Senate: Abdul El-Sayed in Michigan.

Jewish Voice for Peace Action is building off of the momentum from a string of victories for the insurgent left in Democratic primaries, where voters have repeatedly chosen outspoken pro-Palestine candidates to represent their party in the November midterms. The nominations signal a sea change in the Democratic Party and its electorate — adding a new class of members to Congress willing to question the United States’ unconditional support for Israel and putting heat on an entrenched political establishment.

“Abdul has been a stalwart and unapologetic defender of Palestinian rights and freedom, and his campaign has demonstrated a moral consistency that centers justice and equality for all people,” said Beth Miller, JVP Action’s political director. “This campaign is a historic opportunity to bring a leader into office who will fight for our communities here at home, and to reimagine a US foreign policy that supports freedom and justice, not genocide and apartheid.”

Ahead of the August 4 primary, El-Sayed is locked in a contentious three-way race with Rep. Haley Stevens, D-Mich., a centrist lawmaker with the backing of the Democratic establishment and the pro-Israel lobby, including its flagship warhawk lobby group, American Israel Public Affairs Committee; and State Sen. Mallory McMorrow, a self-styled progressive who has drawn endorsements from figures like Sen. Elizabeth Warren, D-Mass., and the liberal pro-Israel group, J Street.
