Rory Stewart walked across Afghanistan, was an elected politician, served as a senior British government minister, and was a visiting fellow at Yale University. Today he is the host of a highly successful podcast— "The Rest Is Politics"— and outgoing president and advisor of the global anti-poverty charity, GiveDirectly. By any measure, he is a man of many parts.

In our podcast, Stewart raises the alarm about threats to democracy in Europe and the U.S., explains his detailed understanding of common ground, and discusses the stark difference between skills needed to win political office and what's needed to govern well.

We ask him about the parallels between U.S. and U.K. politics, the threats to democracy from populism, and how other elected politicians overseas view America's current political division and dysfunction. "The U.S. public square really looks incredibly divided," Rory Stewart tells us.

We also discuss his outspoken new memoir about his years in the U.K. Parliament and government, "How Not To Be a Politician."
