1199SEIU endorses Mamdani as key labor groups line up behind Democratic mayoral nominee
1199SEIU, the largest healthcare union in the country, endorsed Zohran Mamdani on Friday as major organized labor groups coalesce behind the Democratic mayoral nominee following his upset primary win over former Gov. Andrew Cuomo.
Mamdani has already garnered the backing of DC37, 32BJ, the Hotel Gaming and Trades Council and the United Federation of Teachers, among others. Many of those unions previously supported Cuomo, including 1199.
1199SEIU President Yvonne Armstrong cited Mamdani’s push for affordability in the city as a major reason for their support.
“Working people across New York City are uniting to defend our neighborhoods and our city from unprecedented attacks from extremist politicians and their billionaire donors who are taking away healthcare, ripping families apart and endangering our democracy,” Armstrong said in a statement.
