N.B.: Do not click the link if you are under the impression that Obama and the Congress are doing a good job with the economy. Mr. Cavanaugh will harsh your mellow.
Related: Brian Doherty's Radicals for Capitalism is an interesting and concise history of the libertarian movement in America, which goes back a lot further than Ayn Rand and (imao) has a lot of crazy uncles in the attic. Lots and lots of short bios of all the major figures in the movement, some analyses of why the LP hasn't achieved much as a third party, and a lot of background on the anarchist/Left/"soft" libertarians that I frankly hadn't been aware of. Highly recommended.
