Interesting question. I often think how amazing these commentators all come out of the comedy world. And now, to some degree or other, they're taken seriously. I think Stewart is smartest & wittiest, though he just may have better writers. Maher I usually agree with, but he comes across as obnoxious and pompous as all the right wing psychos on Fox. Miller used to be really talented, I thought, but I think he's lost it. Plus I always have the sneaking suspicion that he really isn't a right winger at heart, but there were so many liberal comics he figured to carve out a new career being reactionary and getting a regular gig on Fox.
