It's been called the starkest choice in years, between two men with sharply different backgrounds, views, and prescriptions for fixing the country's problems. Mitt Romney and Barack Obama have spent hundreds of millions of dollars to tell their own stories, but in The Choice 2012, FRONTLINE goes far beyond the headlines on a journey deep into their worlds, among their friends and family, critics, and closest colleagues, to understand what drives these men. Based on dozens of new interviews and hundreds of hours of research, FRONTLINE's authoritative profiles that emerge are also a portrait of America in an era of uncertainty and a guide to the choices that lie ahead.
