The one real hope I have for the Iraq war to end is the fact that a lot of the Republicans who survived this year didn't survive by much. Such near death experiences is likely to change one's thinking. And its clear that the Iraq war is the leading cause of political death and near-death.
There are a whole bunch of Republicans who don't want to run with the Iraq War weighing them down for a second election cycle. So start seeing some heat from Republicans to end the war. Quiet heat, but heat.
Naturally the one Republican who controls our fate in Iraq is the only one who will never face the voters again.
