Two conversations on The Point. Host Mindy Todd talks to author and presidential historian Doris Kearns-Goodwin about her new book, The Bully Pulpit: Theodore Roosevelt, William Howard Taft, and the Golden Age of Journalism. Also, a conversation with five-time Grammy nominee Tierney Sutton, a musician-singer who writers say uses her voice like an instrument. She'll be on Cape Cod for the annual Jazz Fest Falmouth.
