Shoot, I was just about ready to post this.
Not just because of this, but I'm starting to think Romney has a very serious chance of winning Iowa. A win in Iowa will almost certainly lead to a good win in New Hampshire, and at that point, barring a major scandal (doubtful, as if there was anything worse on Romney, it would have been exploited by now), it will be extremely difficult to stop him.
I've said this before - Romney needs to campaign hard in Iowa. He has the resources and organization to win there.
