McCain is in denial with regard to his anger problem.

Reasons to agree

1. When asked about his temper, McCain has portrayed himself as angry about issues. "Do I feel passionately about issues? Absolutely," McCain has said. "Do I get angry when I see pork barreling and wasteful spending? Absolutely." But McCain's outbursts have not been directed at policy issues or waste. Instead, even if they are longtime friends, he explodes at people who disagree with him or who tell him they cannot support him.
2. McCain's aides say that McCain himself was the last to recognize that he had a reputation as a hothead, and used to rail at them in private every time a public commentator suggested he had a problem, shouting, "I do not have a temper. I just care passionately."
