As regards the war funding bill, Democrats are fatigued. So here's a word of non-partisan strategic advice- take a breather. Relax. Just do nothing for while and see if events on the ground change the politics back home.
Anyway, it now seems that Democrats just don't want this fight. From CQ:
"The problem is that we have to provide money for the troops, and if we don't, the Democrats will be blamed," added Rep. James P. Moran, D-Va., a war opponent. "Bush has the bully pulpit, so he will define who is responsible."
