Honestly, I don’t see these going anywhere, because of the gutless leadership in the House and Senate, but Representative Rep. Rosa DeLauro (D-CT) and Senator Hillary Clinton (D-NY) have introduced bills prohibiting the Bush administration from entering into a binding security arrangement with Iraq. They require the President to follow Article II of the constitution, and get the “advice and consent” of the Senate.
You can see the House version here.
FWIW, it should be introduced once a month leading up to election day, just to make Republicans vote for the war, over, and over, and over again.
For the life of me, with a substantial majority of Republicans wanting a pullout, and a president who is less popular than the idea of Britney Spears* as a baby sitter, that the Republican delegation continues to back this failed war of a failed president.
They are drowning, and they are throwing themselves an anvil, and calling it water wings.
*Yes, I know that I have promised not to mention They Who Must Not Be Named, but this is not a discussion of her, rather an invocation.
