It's got to be real embarrassing for them to know that her name was disclosed by Wilson's own Who's Who entry after months of putting him up as the victim.
First of all, nothing embarrasses them. Secondly, they succeeded in casting a cloud over the administration that will never go away. Lastly, there's an old saying that "There's no defense against a liar." The Dems will continue to lie, cheat, and chip away at the administrations credibility until they reclaim the White House.
I don't think they're capable of embarrassment. You have to have a conscience in order to be embarrassed.
They are just quivering masses of Bush-hatred.
