'McCain "often insults people and flies off the handle," the New York Times reported. The Arizona Republic was writing about his "volcanic temper" the last time he ran for president ... His former colleague in the Senate, Republican Bob Smith, says McCain is a nutter: "I have witnessed incidents where he has used profanity at colleagues and exploded at colleagues ... He would disagree about something and then explode. It was incidents of irrational behavior. We've all had incidents where we have gotten angry, but I've never seen anyone act like that." Former Congressman John LeBoutillier, another Republican, says this: "I think he is mentally unstable and not fit to be president".'
