What’s behind this year’s populist explosion? In the latest episode of Deep Dish, Council vice president of studies Brian Hanson interviews John Judis, author of The Populist Explosion, to put the year’s political movements—from Brexit to Trumpism—into historic context. Hanson then sits down with Council President Ivo Daalder and Chatham House Director Robin Niblett to discuss the implications of populism for the established world order.
