I have to disagree. When they are in the majority, they're pulling out. They saw Duncan's trick for what it was and knew this was not the time.
But in another year or so, I think it's a given they'll leave. Kerry and some others are on record as saying we should get out.
Many of the ones that claimed they wanted troops out now were put on the spot to spot to VOTE that way and when push came to shove they refused. There was no trick, just a simple vote that could be judged on its merits.
Please notice that almost all the pull out now crowd was hushed at that time. Sure some still call for it now and they are akin to the ones in Iraq that when we do finally pull out will claim they were right all along and that their actions drove us out.
Israel deals with that very thing and look what was claimed when they did leave Gaza!
Many will talk impeachment but very very few will actually persue it. I dare them to try.
