Hillary will folow the same path Nixon did with Vietnam. Nixon wanted to pull out in 1968, but knew he’d never get re-elected if he did. He spent the next four years trying to get out gracefully “peace with honor” and making a mess of the war. As soon as he go re-elected, he pulled the troops out and left Vietnam on its own.
Hillary will do the same thing in Iraq. Obama will pull them out first chance he gets.
Just last week she (on the weekend news talkies, IIRC), she committed to pulling the troops out beginning January 20, 2009. If she straggles them out, she could lose the backing of her party and her public.
