This is absolutely essential. Otherwise, Bush could and probably will claim that he still has the congressional authorization to wage more blind, stupid, incompent war.
Congress must pass a motion clearly stating that it has formally, officially, conclusively and definitively taken away Bush's war powers and authorizations.
Failure to do so puts the nation at risk of being thrown, dragged, stumbled into another war without end without plans.
This should be one of the elements of the legislation the Dems commit to passing in the first 100 hours.
Now, in the senate, Joe Lieberman will probably block it. No matter. There should be enough sane Republicans who want to keep their jobs after the 2008 elections who will support this legislation.
It will be a real test for the presidential candidates. Will those who voted FOR the war in 2002 vote against it this time? There are no good excuses any more, unless, you are a war hawk Bush sycophant like McCain or Lieberman.
This should be a no-brainer for the dems. Of course, Hillary has been trying to walk the fence on this one and there may be some sort of tacit agreement amongst the dem insiders to save her from having to take a stand. That would be totally unacceptable. The war was THE issue that affected the 2006 elections. Failure by the dems to take this first step would be outrageous. This is an easy question. They don't have to decide about when or if to pull out the troops. They just have to make it clear to Bush he can't start a war anywhere else.
