WASHINGTON — Sen. John McCain, who faced down his captors in a Vietnam prisoner of war camp with jut-jawed defiance and later turned his rebellious streak into a 35-year political career that took him to Congress and the Republican presidential nomination, died Saturday after battling brain cancer for more than a year. He was 81.
