The Neo-Cens have been joined by any number of former revolutionaries like Carl Davidson and Angela Davis.
Just a clarification. In the case of Davidson, former does not mean last year. He has not really been identified with revolutionary politics since Joe Cocker was a big star. In the 1990s, he was part of the Cruise-Missile left pushing for NATO intervention in Yugoslavia. He was also gung-ho for invading Afghanistan to root out terror. Here's a reply to Davidson from Jose Perez of Marxmail:
