Johnny Hothead

John McCain is a hothead. He has a terrible temper. His brain is wired "impulsive", which is probably why he picked Sarah Palin, someone he had met just once, as his running mate. (Would you make someone guardian of your children that you had only met once? Of course not. But McCain just rashly chose the guardian of your children's government -- on a whim.) Tellingly, when McCain was a two-year-old, he'd have tantrums where he'd hold his breath until he passed out! He is not wired for calm, reflective leadership.

Kansas City Star: McCain's history of hot temper raises concerns

John McCain made a quick stop at the Capitol one day last spring to sit in on Senate negotiations on the big immigration bill, and John Cornyn was not pleased.

Cornyn, a mild-mannered Texas Republican, saw a loophole in the bill that he thought would allow felons to pursue a path to citizenship.

McCain called Cornyn's claim "chicken-s---," according to people familiar with the meeting, and charged that the Texan was looking for an excuse to scuttle the bill. Cornyn grimly told McCain he had a lot of nerve to suddenly show up and inject himself into the sensitive negotiations.

"F--- you," McCain told Cornyn, in front of about 40 witnesses.

It was another instance of the Republican presidential candidate losing his temper, another instance in which, as POW-MIA activist Carol Hrdlicka put it, "It's his way or no way."

There's a lengthy list of similar outbursts through the years: McCain pushing a woman in a wheelchair, trying to get an Arizona Republican aide fired from three different jobs, berating a young GOP activist on the night of his own 1986 Senate election and many more.

At age 2, McCain's tantrums were so intense that he'd hold his breath for a few minutes and pass out. His parents would dunk him in cold water to "cure" him, he wrote in his memoir, "Faith of My Fathers."
