Drawing on a quarter-century's work, Fred I. Greenstein, one of our keenest observers of the modern presidency, provides a fascinating and instructive account of the qualities that have served well and poorly in the Oval Office from Franklin D. Roosevelt's first hundred days to the beginning of George W. Bush's presidency. Greenstein offers a series of bottom-line judgments on each of his twelve subjects and a bold new explanation of why presidents succeed or fail. Previous analysts have placed their bets on the president's political prowess or personal character. Yet by the first standard, LBJ should have been our greatest president, and by the second the nod would go to Jimmy Carter. Greenstein surveys each president's record in public communication, political skill, vision, cognitive style, and emotional intelligence--and argues that the last is the most important in predicting presidential success.
