Turn on you? There are times I don't agree with Jon Stewart and his criticisms, but I agree with the idea that he seems to be fair about taking both side to task for stupidness. And, just because a politician/official is on "our side" doesn't make him/her incapable of doing dumb things. Paying attention and calling them on it is an excellent way to keep them focused on priorities, an satire has always been a great tool for that – something Stewart does well. For the times when he "turn(s) on you," change the channel.
