What's wrong with the Dems.
So, turn one of the lefty wingnuts loose. Let somebody go out and make some accusation, that undercuts the White House's message for the day. Something informal but good enough to be repeated like, "you know Kanye West was kinda right. I mean, if you look at the programs Bush has cut and his dogged insistence on maintaining the deficit building tax cuts, you just gotta wonder."
Or attack the Iraq policy for god's sake including an inflammatory word like "incompetent."
Don't worry if it ruffles feathers, that's the whole point. The salaciousness of it is what gets it repeated. It puts the White House on the defensive on an issue where its weak and forces their images off the talk show lead. They're weak right now. The press wants you to attack.
And, you don't have to pretend that this person speaks for the party. When Chris Matthews or Russert or whoever tries to trap you, just don't take the bait.
"Mr. Reid, do you believe that Bush doesn't care about black people."
(chuckling) "well, I've worked with Representative (blank) for yearsm and I know he is very passionate about equality and a very courageous politician, I'm sure he wouldn't make those comment if he didn't see a justification."
Fill this void. View it as a gift. You are viewed as a party with no positions, but in fact, it is the lack of passion that turns voters unsure. It's like Colbert says, "without anger, how can I tell how you feel."
