For my money, McCain is just a radically unreflective guy who believes whatever he believes because he believes it, and wild horses won’t make him think that there is anything that needs explanation or justification—particularly not any supposed incoherence between what he believes right now with what he believed 20 minutes ago.
In his unreflectiveness, he’s a lot like another president we have known all too well, and for too long. But the differences are worth noting. One: McCain does, indeed, change his views, and indeed with no obvious pattern—more like a kind of Brownian motion or random walk. Two, for all his brash, ornery, Naval-Academy hubba hubba, I think he has at least a few shreds of human decency in him and that in itself, at the moment, sounds refreshing.
Oy, how little we settle for. Talk about defining leadership down.H/T: Tyler Cowen
