The word that best describes how former Vice President Dick Cheney, who wielded the responsibilities he undertook in public affairs over a long career, began improbably early in life and extended into years of repudiation by his fellow partisans, is unintimidated.

He was unintimidated by his rise to become White House chief of staff at age 34 in 1975, after flunking out of Yale University and not finishing his Ph.D. at the University of Wisconsin (while his wife, Lynne Cheney, earned hers).
