In the course of my roughly three-quarters-of-a-century-long life, I’ve lived in just three cities: Los Angeles, New York, and Washington, D.C. By year’s end, there’s a decent chance that all three of those cities will have a socialist mayor. Just to be clear, despite the fact that I’ve been an avowed democratic socialist in all three cities—for all of my adult life, in fact—I’m claiming no credit for their new socialist proclivities.
