James David Barber, author and political scientist, discusses his book, "The Pulse of Politics: Electing Presidents in the Media Age." He explains the premise of his beliefs that presidential elections run a cycle of "conflict, conscience, conciliation," and how media affects this. He uses examples of elections from Teddy Roosevelt to Jimmy Carter. Presidential campaign songs are played throughout the interview. A record is played to hear the voices of Teddy Roosevelt and Franklin D. Roosevelt.
