US Senator Bernie Sanders started his career in electoral office in 1981, as the democratic socialist mayor of Burlington, Vermont. Now, 44 years after Sanders won his first mayoral term, Zohran Mamdani seeks to become the democratic socialist mayor of New York City. Sanders endorsed Mamdani before New York City’s June Democratic primary and has been an enthusiastic supporter ever since. You’re running for mayor of New York City. New York City is not for sale.” That will send a message to every community in America that real change is possible.
