This volume examines the nature and effects of the separation of the US executive and legislative branches, followed by a comparison of presidents and their relative advantages in working with Congress. The author treats specific developments in presidential-congressional relations by analyzing the experiences and styles of Lyndon B. Johnson, Richard Nixon, Gerald Ford, Jimmy Carter, Ronald Reagan, George Bush and Bill Clinton. A new expanded chapter on Clinton reviews the latest dramatic phases of Clinton's experiences with Congress and provides a basis for analyzing one of, arguably, the most interesting presidencies in recent times, and the workings of a separated system.
