McCain's temper

I've heard about this before and it's very disturbing. Take a look at this article called "McCain's temper back on campaign's front-burner":

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.

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.

"We have had eight years of cowboy diplomacy, and McCain is even more of a cowboy than the current president," said Roger Salazar, a Democratic political consultant who worked for John Edwards in 2004. "The public wants somebody who is strong but can sit across from allies and adversaries without lunging at them."

This is very disturbing. We really need someone with a cool head leading our nation. That should go without saying.
