No figure in American public life has had such great expectations thrust upon him, or has responded so poorly. But Ted Kennedy -- the youngest of the Kennedy children and the son who felt the least pressure to satisfy his father's enormous ambitions -- would go on to live a life that no one could have predicted: dismissed as a spent force in politics by the time he reached middle age, Ted became the most powerful senator of the last half century and the nation's keeper of traditional liberalism. As Peter S. Canellos and his team of "Boston Globe" reporters show in this revealing and intimate biography, the gregarious, pudgy, and least academically successful of the Kennedy boys has witnessed greater tragedy and suffered greater pressure than any of his siblings. At the age of thirty-six, Ted Kennedy found himself the last brother, the champion of a generation's dreams and ambitions. He would be expected to give the nation the confidence to confront its problems and to build a fairer society at home and abroad.
