Oh, I know there is speculation- that's fairly old news. But Buck seems to be saying it's already decided. I didn't see any mention that it's a done deal.
But in terms of trial balloons, the left is going crazy about it, so maybe that's good or maybe that's bad. Do you want loud Rock&Roll or do you prefer a elevator music approach.

Personnally I would prefer Jon Stewart over Triumph the insult dog- mainly because "poop" would probably be mentioned less. And I think if Bush had Steward the Left would be stunned. And that's got to be worth something:)
And it's following the tradition of if you complain about the chow, you should cook it.
