IS KRAUTHAMMER AN ESTABLISHMENT CONSERVATIVE?

I've thought of him as a standard-issue wingnut hack, somewhat more extreme than George Will.  OTOH, I suppose the talk radio wackos will accuse him of being a RINO or something because of these lines:

Led by Sens. Mike Lee and Ted Cruz, the GOP insurgents are threatening to shut down the government on Oct. 1 if the stopgap funding bill contains money for Obamacare. This is nuts.
