There's a saying in libertarian circles, that if a Democrat, a Republican and a Libertarian get together to debate politics soon the Democrat and Republican will join forces against the Libertarian. True to my experience.

Huffington Post is reporting that your next regular columnist for the New York Times will be…William Kristol.A pretty uninspiring choice. It means the Times op-ed page will be well-represented by big government liberals (Krugman, Herbert), big government moderates (Friedman, Kristof), and big government conservatives (Brooks, Kristol). I do believe that just about covers the full range of acceptable political opinion, doesn't it?
Some of the Ron Paul phenomenon might be explained by libertarians being so accustomed to being ignored.

Sullivan's post on the subject makes more sense than (and was posted before) Balko's.

Libertarians are just a discussion group masking as a political party.
