Oh my goodness. I saw McCain during the debates in 2000; he's unstable. When the camera was off him, he paced the stage and muttered under his breath and looked incredibly angry. He turned it on and off in a really bizarre way. Everyone at our table noticed it and commented on it and I think previous to seeing him in person, our senator was going to support him.
Did you read the post here last month when the woman asked him an unedited question in Sun City -- he came unglued. All the other visits on his once-a-year tour of AZ cities were orchestrated, Sun City was not.
You described McCain really well. That man is creepy.
