Is Donald Trump a despot? Could any American president become an authoritarian under our system of checks and balances? Brian Klaas, an expert on dictators, doesn't think so, but he worries about it and thinks other Americans should, too. Klaas, an American based in London, is a prolific political commentator. He is a student of the world's worst regimes, and comments frequently on threats to democracy around the globe. Klaas is a fellow in comparative politics at the London School of Economics and the author of, "The Despot's Apprentice: Donald Trump's Attack on Democracy," newly published by Skyhorse.
