New York —

Outside Rep. Adriano Espaillat’s primary night party, four men on the sidewalk were dressed in full neon sequins, trying to get the party started. Inside, the bar had barely opened.

Espaillat spent 20 years trying to get to Washington and another 10 years in Congress. He arrived to give his concession speech and left in under 10 minutes.

Meanwhile, the real party was going on about three miles away. That’s where Zohran Mamdani was completing his victory lap of three celebrations with candidates who likely would not have gotten near Congress without his endorsements, just a year after he stunned the political world by beating Andrew Cuomo in the Democratic mayoral primary.

“We are showing that last June, a year ago tomorrow, was not an anomaly,” Mamdani said. “It was not the end. It was the beginning.”
