Mickey's take on health care is pretty formulaic at this point, so there really isn't much to examine. The man has literally three concepts that he trots out to explain every new development:
Use: Any time a liberal attempts to make anything better.
Why: Liberals are evil, scheming bastards who don't actually want to ever accomplish anything. Also, they once called Mickey a "bald jerk" and he will never, ever forgive them.
Use: Any time a politician attempts to kill the useful bits of health care reform, no matter how obviously nonsensical or venal his/her motive.
Why: Mickey can't argue that various centrist democrats have been bought by the industries they purport to regulate -- this would violate his core thesis that liberal democrats (Dick Durbin! Boo! Hiss!) are to blame for all the evil in the world -- so he attributes the centrists' perfidy to the fear that the public simply hates subsidized universal health care. Because ... well, because it's made by liberals! (see "Kabuki")
Use: To explain why health care is still alive, despite its many setbacks (see "Id").
Why: Democrats are evil, scheming bastards who pretend to want to accomplish things only to extract money from interested parties.
So, in summation, Mickey Kaus has his head so far up his ass that he thinks politicians act in fear of the voting public and treat corporate donors like suckers.
