Some Democrats went to Iraq to visit the troops, including my old crazy Congressman Jim Moran from Northern Virginia. This is a guy who got into a fight with an eight year old and claimed the kid tried to carjack him. Anyway, they found that some joker had handed out biographies of them to the troops and Iraqis with selected quotes calling the war a failure and so on. Now they are upset, and said that they were "slimed". I think they just need a thicker skins.
