How extensive was Buckley's influence?

Posner has some interesting thoughts. What I can't stand is the incredible, shocking ignorance of those who claim that free market thought in American began with WFB. The Mises Institute has made available vast quantities of books and publications--Nock, Garrett, Flynn, Hazlitt, Mencken, and on and on--that were far better than the stuff you get from National Review today. Posner doesn't seem to know anything about this. So far as I can tell, the claims about the originality of WFB and the NatRev are wholly mythical -- but for the addition of Cold Warism, which seems like an anachronism today in any case.
