It won't stop because they now know the Majority do not hold Bush accountable, of those that do hold him to blame, only about 22% believe it wholely on his shoulders and have intense hatred. and 3/4ths hold local/State accountable while only 2/3rd's hold Feds accountable. This when the facts hadn't been loudly trumpeted on most of our numedia! Infact, while much of our nuMedia was hyperventiliating and spreading erroneous information.
The MSM, of course, feels it just hasn't got it's message out and will keep shouting because we're too stupid to demand the President's impeachment for Nature and Dems incompetance.
The Dems will keep going because the Dems are in trouble in LA. This will reflect badly on all of them even out of state, so they are huddling up.
Here in Michigan I have seen and talked to a lot of people in the last few days and the truth, maybe sadly, is that they aren't really following this except in the broad strokes (a devastating natural disaster with tens of thousands of displaced people and confusion over why people were shooting at rescuers). At the end of the day they can't separate the cause (the hurricane) from the rescue effort. And that's going to continue because of the long road ahead...they will judge on the rebuilding and care for the displaced, not the few days in between.
