If you want to know more about the character of John McCain, I haven’t found anything better than this story, by Michael Lewis, in which he discusses McCain’s relationship with Morris Udall, the Arizona liberal congressman with whom McCain would become lifelong friends.  An excerpt:

By 7:30 we were on the road, and McCain was reminiscing about his early political career. When he was elected to the House in 1982, he said, he was “a freshman right-wing Nazi.” But his visceral hostility toward Democrats generally was quickly tempered by his tendency to see people as individuals and judge them that way. He was taken in hand by Morris Udall, the Arizona congressman who was the liberal conscience of the Congress and a leading voice for reform. ...

“Mo reached out to me in 50 different ways,” McCain recalled. “Right from the start, he’d say: ‘I’m going to hold a press conference out in Phoenix. Why don’t you join me?’ All these journalists would show up to hear what Mo had to say. In the middle of it all, Mo would point to me and say, ‘I’d like to hear John’s views.’ Well, hell, I didn’t have any views. But I got up and learned and was introduced to the state.” Four years later, when McCain ran for and won Barry Goldwater’s Senate seat, he said he felt his greatest debt of gratitude not to Goldwater--who had shunned him--but to Udall. ...

For the past few years, Udall has lain ill with Parkinson’s disease in a veterans hospital in Northeast Washington, which is where we were heading. Every few weeks, McCain drives over to pay his respects. These days the trip is a ceremony, like going to church, only less pleasant. Udall is seldom conscious, and even then he shows no sign of recognition. McCain brings with him a stack of newspaper clips on Udall’s favorite subjects....

Aside from a congressional seal glued to a door jamb, there was no indication what the man in the bed had done for his living. Beneath a torn gray blanket on a narrow hospital cot, Udall lay twisted and disfigured. No matter how many times McCain tapped him on the shoulder and called his name, his eyes remained shut.

A nurse entered and seemed surprised to find anyone there, and it wasn’t long before I found out why: Almost no one visits anymore. In his time, which was not very long ago, Mo Udall was one of the most-sought-after men in the Democratic Party. Yet as he dies in a veterans hospital a few miles from the Capitol, he is visited regularly only by a single old political friend, John McCain.

A big thanks to John Hinderaker of Powerline for pointing out this story and editing the excerpt beautifully.
