With all eyes on the consequential presidential election already underway, Martha talks this week to the famed political operative, James Carville, and the director of the new documentary about his work, Matt Tyrnauer. The documentary, called "Winning is Everything, Stupid!" chronicles how Carville has practiced a brand of old-school political gamesmanship from the 1992 Bill Clinton campaign through today. The film looks at his longtime marriage to Mary Matalin, his partisan opposite, and Carville's mastery at shaping messages. Don't miss this timely and insightful discussion.
