Overview

• Senator Elizabeth Warren campaigned with Zohran Mamdani and formally backed his plans to build affordable housing, expand childcare and tax the ultra-rich.
• Senate leaders Chuck Schumer and Hakeem Jeffries and Sen. Cory Booker have withheld endorsements, reflecting establishment unease over his democratic socialist label.
• Billionaire investor Bill Ackman has pledged hundreds of millions of dollars to independent efforts supporting Andrew Cuomo and Eric Adams against Mamdani.
• A New York Solidarity Network poll of 800 Jewish voters finds just 37% would back Mamdani in a general election, with safety and Israel-related concerns driving much of the opposition.
• New York City’s ranked-choice general election remains fragmented among Democratic, independent and Republican contenders vying to unseat Mamdani.
