In the week leading up to the election, we explore our final #30Issues topic: character and temperament. Listen to the audio history of American presidents and how their personal characters have been called into question. Then, David Greenberg, professor of history, journalism and media studies at Rutgers University and author of Republic of Spin: An Inside History of the American Presidency, discusses how president's personalities have informed their legacies or impacted their election chances in the past.
