That is because Eric Adams was propelled into office by an outer borough coalition of older, working class, black, union, and moderate voters focused on crime and public safety.
Whereas Zohran won with a coalition largely comprised of younger, college-educated renters, transplants, omnicause leftists, and downwardly mobile elites.
The latter buy tribe merch at pop-ups on weekday afternoons. The former do not.
Could be wrong, but I can’t say I remember seeing pop-up shops selling Eric Adams merch.
