'Don't Sabotage Mamdani': 30,000+ Petitioners Urge Gillibrand to Get Behind Progressive NYC Mayoral Candidate

Supporters of progressive New York mayoral candidate Zohran Mamdani are putting pressure on reluctant centrist Democrats to fall in line and back his candidacy after he scored an upset win in last month's Democratic primary.

Progressive advocacy organization Our Revolution has gathered more than 30,000 signatures in a petition urging the Democratic political establishment to not sabotage Mamdani's candidacy by backing independent candidates such as incumbent Mayor Eric Adams or former New York Gov. Andrew Cuomo.

The organization said Wednesday that it attempted to deliver the petition to the Manhattan offices of Sen. Kirsten Gillibrand (D-N.Y.), who is one of many big-name Democrats in the state who have yet to back Mamdani's general election candidacy, but was denied access to the building by security.

"After multiple calls to both the NYC and D.C. offices, staff refused to accept the petition in person and directed organizers to submit it online—despite the urgent, NYC-specific nature of the issue," Our Revolution claimed.

The event was organized to draw attention to the double standard and disconnect between party leadership and grassroots voters, especially in races where big money interests—some with ties to the Democratic Party machinery and others without—work behind the scenes to push out progressives.

"Democratic leaders love to talk about unity—until a progressive wins," said Joseph Geevarghese, executive director of Our Revolution. "Every cycle, we're told to fall in line for the good of the party. Well, Zohran Mamdani is the nominee—and yet the establishment's silence is deafening. It's time for party leaders to live up to their own standards and stand with Zohran against these billionaire-funded attempts to undo the will of the voters."

The action was first reported by Politico, which also reports that a dozen chapters of progressive organizing group Indivisible are writing letters to Sen. Chuck Schumer (D-N.Y.), Rep. Hakeem Jeffries (D-N.Y.) and Democratic New York Gov. Kathy Hochul to urge them to get behind Mamdani.

"The party should be celebrating and analyzing this win as we prepare for the fight of our political lives in 2026," wrote Indivisible signatories. "At a time when Democrats have struggled to connect with voters and build credibility, supporting and learning from Mr. Mamdani's playbook is paramount."

Additionally, Politico reports that Jasmine Gripper, the co-director of the New York Working Families Party, is also urging the state's Democratic leadership to put aside their reservations and back the party's nominee. Gripper noted that Mamdani has won the endorsements of his fellow New York state assemblymembers from across the political spectrum, which should ease their concerns that his candidacy is out of the mainstream.

"The Mamdani tent is big enough for everyone," Gripper said. "Any leader who is serious about building a base of energized voters and wins would be smart to join us."

A poll released by political consulting firm Slingshot Strategies on Wednesday shows that Mamdani currently leads among voters, although that advantage could shrink should either Adams or Cuomo drop out of the race to endorse the other's candidacy.

Overall, the poll showed Mamdani scoring 35% of the vote, compared to 25% for Cuomo, 14% for Republican Curtis Sliwa, and just 11% for Adams. Mamdani also held the highest net favorability of the major candidates at +4 percentage points, whereas Cuomo was underwater by 2 percentage points and Adams had a net favorability of -34 percentage points.
