This is what a Republican -- George Will -- has to say about John McCain:
Although his campaign is run by lobbyists; and although his dealings with lobbyists have generated what he, when judging the behavior of others, calls corrupt appearances; and although he has profited from his manipulation of the taxpayer-funding system that is celebrated by reformers — still, he probably is innocent of insincerity. Such is his towering moral vanity, he seems sincerely to consider it theoretically impossible for him to commit the offenses of appearances that he incessantly ascribes to others.
And that ain't the half of it.
Campaign finance and its reform are a labyrinthine topic, but even if you can't follow all the twists and turns of Will's story, you will not come out of the labyrinth with your admiration for the war hero undamaged.
H/T: Icepick, who adds the coup de grace:
He's got all of Nixon's faults and none of his virtues, plus he's every bit as desperate for attention as Bill Clinton.
