FRONTLINE investigates the lives and views of Sen. JD Vance and Gov. Tim Walz as they run for vice president. Drawing on interviews with those who know Vance and Walz well — friends, advisors, journalists and political insiders — the documentary traces how these two men from the middle of America found their opposing political voices and explores the ideas and influences they would bring to the White House.

From his chaotic childhood to the White House, JD Vance embodies the MAGA-style revenge of America. To recount the ideological journey of the Vice President of the United States, Thomas Snégaroff and David Thomson met with a dozen people who have been close to him throughout his life. They reveal who Vance truly is: how the man evolved ideologically and how he transformed politically. These encounters and interviews with his closest associates, including his mother Beverly and his mentor, David Frum, uncover the secrets of his ambitions and plans to transform America and Europe.
