An angry, profane exchange between Sen. John McCain and another Republican senator last week prompted a new round of questions Monday about whether McCain's legendary temper is becoming a liability to his campaign for the presidency.
In a private meeting just off the Senate floor, McCain (R-Ariz.) got into a shouting match Thursday with Sen. John Cornyn (R-Texas) over details of a compromise on immigration legislation. Cornyn accused McCain of being too busy with his campaign to take part in the negotiations, prompting McCain to utter "F... you."
McCain spokesman Danny Diaz acknowledged Monday that a "spirited exchange" had taken place, but said news reports had exaggerated its intensity.
McCain's political handlers have plenty of experience in explaining his salty language and strident attacks. His temper has ranged far and wide, directed at other members of the Senate, congressional staffers, government agency chiefs, corporate chieftains, military officers and teenage campaign volunteers.
McCain has shouted at people for any number of reasons, including errors of judgment, disagreements on public policy and even how to set up a podium.
"In McCain's world, there aren't legitimate differences of opinions," said David Keene, chairman of the American Conservative Union, which differs with McCain on some issues. "There is his way and there is evil. That is how he approaches issues. That is one of the reasons for conservative nervousness about him."
His temper has been an issue for years.
In the 2000 presidential bid, McCain was dubbed "Senator Hothead" by Newsweek. That year, he won endorsement from only a few Senate colleagues. His frequent attacks and volatile personality were most likely to blame. "McCain notes," which offer apologies after heated words, are held by many members of Congress.
McCain has written about what he describes as his impatience. "Although I try to refrain from being intentionally discourteous, I am demonstrative in showing my displeasure. I am often impatient and can speak and act abruptly," he wrote in "Why Courage Matters" in 2004.
In a 1999 interview with The Times, McCain said: "I do everything I can to keep my anger under control. I wake up daily and tell myself, 'You must do everything possible to stay cool, calm and collected today.' "
