I think the impetus is right, in order for Democrats to gain control of the White House and Congress they need to buck Republican decisions and stand firm against them. I don't think in this case it will make enough of a difference. Bush has lots of rope and he's already damn near hanged himself with it loads of times...
But then, part of me wants to run... the trouble is I can't decide if I want to run for office or run away!
I am so tempted to give up politics altogether... it makes me even more cynical than normal, which is not a good thing.
