Not a liberal?: I dunno, I think Carlin is a liberal (notice small "L"). I think he's smart and I think he wants people to think for themselves, but note a quote of his from an interview he gave promoting "Jersey Girl":

What would you change about the government if you could?

Everyone should have the right to shelter and food and a way to get a job to provide shelter and food on your own. The government should provide for people. There ought to be a way to take care of human needs, and we haven't worked very hard at that. That's my complaint. They say underneath a cynic is a disappointed idealist. And that is what I am. And that flame can be rekindled, no doubt.
