Journalist and author Jonathan Freedland asks, in a quick tour through the history of the US presidency, what qualities a great president needs and what can be learnt from the likes of Theodore Roosevelt, JFK, or perhaps even Richard Nixon, about what it takes to make a mark in the White House. He is helped by notable contributors, including James Naughtie, Shirley Williams, Douglas Hurd, Simon Hoggart, and Bonnie Greer, who each give their frank assessments of some of America's greatest presidents.
