The Dishcast is hosted solely by Andrew Sullivan, the writer behind the Weekly Dish on Substack, and consists of extended one-on-one interviews rather than panel discussions or narrated storytelling. A recurring format feature is Sullivan's personal opening, in which he discusses his health, mood, current events, or life in Washington, DC before introducing the guest and topic. Guests are typically journalists, historians, and political writers, including figures like Jeffrey Toobin, Eli Lake, Jonah Goldberg, George Packer, Mark Halperin, and historian Tom Holland, who appears as a recurring guest. Political episodes cover constitutional mechanics such as the presidential pardon power, U.S. foreign policy debates over Israel and Iran, and the history of American political journalism from the Drudge Report era through Trump-era media. Other episodes turn to religious and classical history, discussing the origins of Christianity, Roman moral norms, and modern parallels to ancient power politics. A smaller set of episodes focuses on personal or philosophical topics, such as happiness research or the changing path into a writing career. Conversations are unscripted and often argumentative, with Sullivan pushing back on guests rather than simply prompting them. Episodes generally run between 25 and 55 minutes. The show suits listeners already following American political commentary, journalism, and history rather than newcomers seeking primers. Production is a single recurring host format with no narrator or ensemble cast beyond Sullivan and his guest.
