Zohran Mamdani’s dramatic, strong showing in New York’s Democratic mayoral primary, in which he forced a concession from former Gov. Andrew Cuomo, amounts to a massive shot in the arm for progressives and other Democrats who have been imploring their party’s elder statesmen to step aside for a new generation of leaders.

Mamdani said his city would be one "governed as a model for the Democratic Party," which would prioritize the working class and fight Trump.
