Pelosi is a politician and she knows better than to shoot her mouth off about going after Bush. She knows as well as anyone that it will have to be done. Bush knows it too. But it will be done gradually. They have until January and they need to plan this thing out. But there is no way Pelosi is going to squelch investigations into the run-up to the war and the fraud and thievery it spawned--not to mention the torture, the warrantless wiretapping, etc. She's not stupid. Unlike some people.
