"Wonder why?"
For the same reason Republicans are now abandoning the Presiden't s wartime policy in droves and leaving him to twist slowly in the wind: to save their own political ass. You're a smart boy, TB, you can figure it out. Why is it that when Democrats do something self-serving it's because they're Democrats, but when Republicans do it it's because they're politicians?
They're both self-serving and they're both politicians and neither really gives a rat's ass what happens in Iraq as long as they get re-elected.
