After decades of defeats for working people and the Left, it almost felt like a dream to witness Zohran Mamdani make history last night. Sometimes the good guys win. As David Hogg wrote last night, “BREAKING: Not everything has to suck.”

Absorbing the key lessons of this campaign is essential for the fights ahead, not just in New York City but across the United States.

1) Zohran’s victory is a nationwide political earthquake. Huge numbers of voters are sick of the Democratic establishment, and there’s no good reason why his playbook can’t be widely repeated elsewhere. The party’s decrepit old guard is vulnerable, its unpopularity delivered us Trumpism, and it deserves to be displaced everywhere.
