The actual putsch was the defenestration of Murray Rothbard some 30 years ago, but see this American Conservative blog by Jordan Bloom. Jane Mayer of the New Yorker has her own blog, but she ignores Murray's role in the founding of Cato. Of course, I speak of the original Cato, the libertarian powerhouse in San Francisco, not the regime-friendly version in DC.
NB: I get report after report that the entire Kochtopus is in turmoil. They fear that the gravy train is about to leave the station, and they won't be on it. A number of them are right.
