If I’m going to start on McCain, I’ll begin by having what many regard as the cheapest shot of all. He is too damn old.
McCain's political colleagues, however, know another side of the action hero - a volatile man with a hair-trigger temper, who shouted at Senator Ted Kennedy on the Senate floor to "shut up", and called fellow Republican senators "sh-thead ... f-cking jerk ... a--hole". A few months ago, McCain suddenly rushed up to a friend of mine, a prominent Washington lawyer, at a social event, and threatened to beat him up because he represented a client McCain happened to dislike. Then, just as suddenly, profusely and tearfully, he apologised.
There is another sort of age that John McCain has and maybe you have noticed it. It is not shown on his face, which has the same grey look that my own shares and it don’t mean nothing.
No, it is in his eyes. Look at them when next you hear him speak. They appear not connected to what he is saying. They are looking far off into some distant past and into some vaguely perceived future that is not too far away. They are the eyes of an old man. Some of my friends have this look. Not all, but some do. I could describe it better but it is not a place that I want go because to do so I would have to look into a mirror. I don’t do much of that these days. I don't have to because I'm not running for President - or for a place on the golf club committee.
