I wouldn't worry too much about the comedians.
You're forgetting what a goldmine Clinton was for comedians. Diddling around with an intern in the oval office -- man, that is comedy gift wrapped with a little bow on top.
And if you look back at Saturday Night Live in particular, they've always found a way to tweak the incumbent. Look at Dan Ackroyd doing classic bits as Richard Nixon and Jimmy Carter. And Chevy Chase -- he took our blandest President in recent memory (that would be Ford) and made him hilarious. I don't remember who did Reagan and Bush Sr., but plenty of folks made a living off them as well.
I don't remember where, but I saw a quote from Lorne Michaels saying they need to find someone who can do Obama. And McCain -- you could do a whole set of jokes about his temper alone.
And Bush has actually been a tough sell for comedy until the last couple of years. There was a long period in there after 9/11 where he was untouchable as a source for jokes.
So, fear not, maxmordon. The beauty of this country is that we'll go to the polls and elect someone, then the next day we'll start making fun of him (or her).
