13. George H.W. Bush (1)

When George. H.W. Bush left the Oval Office in 1992, rejected after one tumultuous presidential term, his 30-year career in public service came to an abrupt and unexpected end. Despite soaring approval ratings following military victory in the Persian Gulf, his years as president after the war were marked by almost unrelieved decline. A sluggish economy and an earlier decision to raise taxes, despite an explicit campaign oath, led to his defeat. By the end of his term many observers dismissed him as an artifact of an irrelevant Cold War past.
