The other day, I was talking with a guy who said that conservatives have a lot of eggheaded books about philosophy and principles — and that what they lack right now is a popular manifesto for the current moment. I furrowed my brow thoughtfully, unconvinced but not sure how to respond. A little later, it dawned on me. We do have the book: Liberty & Tyranny, by Mark Levin. Many of you know this already and have helped make Liberty & Tyranny one of the best-selling books of 2009. You could do a lot worse than to make it one of the most gifted books of Christmas, too.
