Mamdani is testing his political influence by endorsing three left-wing challengers in key congressional races, including Avila Chevalier, which is considered a politically risky move given Espaillat's status as the informal dean of New York politics. His endorsement typically shifts a race in New York City by about 30%, and he recently appeared in a basketball-themed TV ad declaring, “This is my team. This is our year,” alongside Lander, Avila Chevalier, and Valdez. Mamdani stated that the old way of thinking in politics will lose in upcoming contests, including those in South Carolina and New Hampshire.
