I never really bought it, but at the same time, politics is politics. McCain was hardly the first guy to work hard on his public persona, and, ideological disputes aside, he always struck me as a basically decent person. A little too self-righteous for my taste, but decent.
But now I'm watching him in 2008, his desperation for the presidency driving him to conduct a campaign that's carefully but relentlessly testing ever more contemptible depths of squalor in its attacks on Barack Obama ("he made time to go to the gym but cancelled a visit with wounded troops" is just the latest), and I wonder how he's going to feel when it's all over. Not only will he lose the election, but he's going to wake up one morning and realize that he abandoned his dignity in the process. That's obviously something that's important to him, and even for someone who was never much of a fan, it's kind of sad to watch him give it up so readily.
