That's a cheerful thought! I'd suggest that maybe the Democrats realized what a poor performance Murtha would give, but I don't think they have the ability to see it. Your theory is probably more correct.
For now I don't think the Dems had anything to do with Murtha going on MTP. Cause like you say, he'd have been everywhere had the Dems been hyping it. I think MTP called Murtha and HE agreed to go on.
It's also interesting there's no Repub to counter him. I think this is by design. So okay a lot of them have gone home for the holiday but can't they video those things locally? Maybe the pubbies figured by debating this guy it lends him credibility. Isolate him and he looks like the Moonbat he is.
I'm convinced Murtha was the Dems' Ace in the Hole, to be brought out close to the Iraq final vote coming soon. I'm also convinced, FOLLOW THE MONEY, that Murtha's knee deep in some oil-for-palaces action.
