The whole Sen. Johnson blab-fest on the cable news just shows how DC-centric they are. I am sure everyone is talking about this in Washington, no matter how little they know about A) brain surgery and Sen. Johnson's condition and B) the law on replacing incapacitated Senators. It is the perfect event for such DC folks: there is little hard information going around, it is a small event that could have massive implications for public policy and power, and there is no other political news really to speak of until January 8th, when Romney and all the other 2008 wannabes start announcing.
Washington, it has been said, it is a town that runs on rumors. Nothing could be a better example of this adage than poor Sen. Johnson's current health. It sounds like he could be right as rain in a couple of months and let's all pray for the best.
When thinks for the GOP didn't work out this November, they are left hoping Senator Johnson dies, just like Democrats were waiting on Sen. Thurmond to die or to flip a moderate GOPer (they got Jeffords and Chafee should have joined him).
