Reasons to agree"

1. When McCain ran for the Republican nomination for president in 2000, only four Republican senators endorsed him.
2. "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 Senator Bob Smith, a New Hampshire Republican who served with McCain on the Senate Armed Services Committee and on Republican policy committees.
3. "He had very few friends in the Senate. He has a lot of support around the country, but I don't think he has a lot of support from people who know him well." - Former Senator Smith, who dealt with McCain almost daily.
4. Another former senator who requested anonymity recalled an exchange at a Republican policy lunch. McCain turned on another senator who disagreed with him. "McCain used the f-word," the former senator said. "McCain called the guy a 'sh--head.' The senator demanded an apology. McCain stood up and said, 'I apologize, but you're still a sh--head.' That was in front of 40 to 50 Republican senators. That sort of thing happened frequently."
