You're a NZer right?
P.J. O'Rourke didn't stop being a leftie because he got a job and a haircut. He stopped being a leftie because he's an asshole. (Man, that "evils of collectivism... creating... public-school" line still repulses me on so many levels.)
And don't compare yourself to him; you're funnier than he is.
Also, I have a feeling that this isn't going to be a great term for the National government. But if this is anything to go by that's not going to be for good reasons.
PJ O'Rourke is (supposed left-wing activism from his teen years aside) a lifelong libertarian (not event the good kind). He used to write genuinely funny political satires, but now he just regurgitates right-wing talking points in the Weekly Standard.
