"McCain has always lived for the fight, and he has defined himself most clearly in opposition to an enemy, whether that enemy was the rule-bound leadership of the United States Naval Academy, his North Vietnamese captors, the hometown Arizona press corps that never much liked him, his Republican congressional colleagues, the Reverend Jerry Falwell, George W. Bush, Donald Rumsfeld, Barack Obama, or J. D. Hayworth. He has always been more of an existential politician than a consequential one, in the sense that his influence has derived not from steady, unswerving pursuit of philosophical goals or legislative achievements but from the series of unpredictable—and sometimes spectacular—fights he has chosen to pick. As his daughter Meghan recently wrote, he has always been more of a craps guy than a strategic poker player. He has never been a party leader, like his old friend Bob Dole, of Kansas, or a wise elder, like his colleague Dick Lugar, of Indiana, or a Republican moderate, like Susan Collins and Olympia Snowe, of Maine. He flies solo, first, last, and always, and his paramount cause has always been his own. That is the bracing reality of John McCain. It is the tragedy, too."
