You're right in that Obama will be worsening his caricature as a celebrity, but he can't very well not go-  NBC no doubt required balance in that, if McCain appeared this spring, then Obama had to perform at some point.

Then of course, there's that NBC thing on the heels of the conventions.  I'm sure Jeff Zucker is cringing all over again at just how damn bad Olbermann and Matthews have made him look, but again, he can't get out of it.

We want her/him to shut up because s/he is repeatedly mistaken about the most basic facts in her "arguments," and then when they are pointed out, says things like "well, i don't believe that."

but to you, s/he is the paragon of argumentation.

And calling folks at TL Obama supporters is downright hilarious. You realize that most TL'ers were/are very pro-Hillary, right? We are all about strong women here -- not unqualified women, or women or men who are too simple-minded to know the difference between a talking point and a fact. And that includes devon cooper.

I think Letterman, Ellen, The View, Snl etc are neutral in the celebrity classification. Along with People mag (Obama fam was in what mag?) etc. They all do them to reach a wider audience. Stage speeches in Germany and use outdoor stadiums, not so much  ;)
