Mitch Daniels talks about five books that influenced him. He actually seems to have read the books he is talking about. The list also seems authentic in that Daniels doesn't seem to be trying to please and impress everyone ("From A Theory of Justice I learned ...and from the Summa Theologica I learned..."
But since the list seems to truly represent Daniels' mind, it should be taken seriously. For reasons I can't fully articulate, the list left me a little uneasy about Daniels as a potential President. The list seems to tilt towards different kinds of libertarianism (though thankfully not liberaltarianism.) I'm not so sure about a President whose mind runs the gamut from Hayek to Postrel but maybe not much farther. Though we could do worse...and we are.
