Kerry hasn't changed at all. He has finally revealed himself as the anti-war, foreign nation loving pacifist that he has always been. What you're seeing now is the true sKerry. If by some miracle, he were elected, I think he would pull our troops out of Iraq.
Nixon, without the Nixonian gravitas.
Be Seeing You,

Personally, I am of the opinion that if Kerry somehow manages to win the election, he will find himself unable to pull troops out like he wants (seeing as he has a poor exit strategy) and will end up turning the affair into a real quagmire.
My other fear is that it is a Kerry Administration that would bring about the much worried about "draft" we keep hearing about. The Bush Administration is well aware of the fact that a professional volunteer army is far better than a drafted one. I don't believe the same can be said about the Democrats. Kerry will go in with no plausible exit strategy and no strategy for actually winning, thus stirring up a quagmire that, from a Democrat point of view, will require more troops.
It's just a hunch but I don't doubt that it could happen for a second.
