Americans Against Escalation in Iraq has launched what they call the "Take A Stand Campaign":
The "Take a Stand Campaign" is a nation-wide organizing drive to demand that members of Congress and the Senate take a stand with the vast majority of Americans who want a safe and responsible redeployment of American Forces from Iraq.
Note that they are not talking aboput a "withdrawal", they are talking about a "responsible redeployment" of our troops. The troops may not necessarily get sent straight home, but perhaps they would be in less danger if they were taken out of the middle of the fighting.
They have also launched Iraq Summer:
IraqSummer is a campaign organized by Americans Against Escalation in Iraq and the Campaign to Defend America, designed to turn public opinion against the war in Iraq into political pressure on members of Congress who stand in the way of a responsible end to the war.
They have videos of various Iraq Summer activities such as chasing down Rep Thelma Drake (R-VA) and trying to get her to explain her stance on Iraq, and protest events aimed at Senator Mitch McConnell, plus a whole lot more. Amusing if you like Republican war mongers trying to avoid explaining themselves.
