Volunteers Were the Key to NYC-DSA’s Socialist Sweep

Lost in conversations about New York socialists’ charisma or social media prowess in recent electoral victories is something simple: boots on the ground. New York City DSA mobilized thousands of volunteers and is poised to do so again in the future.

Since the Democratic Socialists of America (DSA) swept the New York primaries in June, conservative and liberal media alike have tried to make sense of DSA’s meteoric rise by tying them to ascendant New York City Mayor Zohran Mamdani and his “kingmaking” abilities. Beyond a cursory nod to the army of volunteers knocking doors and making phone calls, far less has been made of the why behind the volunteer effort that propelled these candidates to victory.

Across NYC-DSA’s slate of endorsed candidates, roughly 8,500 volunteers showed up to knock more than 750,000 doors, with over 810,000 attempted door knocks — for an off-year electoral cycle. Many of these volunteers were part of Mamdani’s 100,000-strong volunteer base, who, still electrified from last year’s win, rolled right into volunteer work for the slate’s ten state-level campaigns.

“I canvassed for the slate in general because I was super excited to capitalize on the momentum from last year with the Zohran primary and general win. That’s how I got started in electoral work in the first place,” said Caroline Hill, a field lead for Samantha Kattan.
