Billionaire supermarket owner John Catsimatidis has warned that New York City could face economic decline if mayoral candidate Zohran Mamdani wins the upcoming election. Catsimatidis criticized Mamdani's promises of free public services, comparing them to policies in Cuba and Venezuela, and questioned Mamdani's qualifications to manage the city's finances and workforce. Despite these concerns, Mamdani recently won the Democratic primary, defeating former governor Andrew Cuomo, and currently leads in the polls. The race has also drawn national attention, with former president Donald Trump expressing strong opposition to Mamdani and reportedly discussing the election with Cuomo.
