DESC: Writing in collaboration with Mark Salter, Senator John McCain of Arizona presents six profiles of public figures who exemplify the qualities of leadership that he values: awareness, timing, foresight, confidence, humility and inspiration. Each of his choices--Lincoln, Churchill, Sadat and Begin; baseball manager Branch Rickey and swimmer Gertrude Ederle; and philosopher of religion Reinhold Niebuhr--faced difficult choices, or hard calls, and McCain walks us through their thought processes, and his own, to show how character and decision-making are intertwined.
