Denvir is forty-two years old and lives in Providence, where he co-chairs a leftist political organization and records “The Dig” from his garage. The other day, he took an Amtrak to Penn Station and a subway up to Washington Heights, for a Mamdani rally in the ornate United Palace theatre. Denvir wore a Henley and a graying beard and had a wheeled suitcase in tow, which was causing a problem with security. Jack Gross, a friend of Denvir’s and the editor of a leftist publication called Phenomenal World, offered to stash the bag in the trunk of his Camry.journey-inline-newsletterinline-newsletter
