New York Times: “Mr. Mamdani is a master of new media, and his rise to power has been driven largely by his ease in front of a camera and his ability to harness the seeming informality of social media to connect with broad constituencies.”“But as mayor, he has also been able to use taxpayer funds to create a sprawling network of hundreds of friendly influencers to boost his priorities, provide positive depictions of his administration and enhance his popularity.”“The administration regularly sends the influencers memos on the mayor’s priorities and encourages them to trumpet his accomplishments, all outside of public scrutiny. The missives are delivered in group chats on Signal, an encrypted messaging app designed to shield posts from public review.”
