For most politicians, boxing is a metaphor. But it never has been for John McCain. Hillary Clinton waved Kelly Pavlik’s gloves during a primary stop in Youngstown, Ohio. It was symbol, a photo op, for a candidate who wanted to be seen as a fighter. But gloves are no symbol for McCain. McCain has worn them. The former Naval Academy boxer says he intends to take up an old fight as he resumes the daily rounds of work as Arizona’s senior senator after the Republican nominee lost in a bruising campaign to Democrat Barack Obama for president.
