McCain's Temper

"The thought of his being president sends a cold chill down my spine," Sen. Thad Cochran (R-Miss.), also a senior member of the Appropriations panel, told the Boston Globe recently. "He is erratic. He is hotheaded. He loses his temper and he worries me."

A former colleague says McCain's abrasive nature would, at minimum, make his relations with Republicans on Capitol Hill uneasy if he were to become president. McCain could find himself the victim of Republicans who will not go the extra mile for him on legislative issues because of past grievances.

"John was very rough in the sandbox," said former senator Rick Santorum (R-Pa.), who is outspoken in his opposition to McCain's candidacy. "Everybody has a McCain story. If you work in the Senate for a while, you have a McCain story. . . . He hasn't built up a lot of goodwill."

Last spring, McCain's confrontational side reappeared during a closed-door meeting of senators from both parties. After spending six weeks away from the Senate, he showed up for final negotiations on a fragile immigration bill, leading Sen. John Cornyn (R-Tex.) to question where he had been. McCain responded by swearing at Cornyn loudly and repeatedly, according to witnesses.

Is John's a steady hand to have perched over the nuclear button? How many times will we hear that this fall?
