Bill Kristol (spit) says that Romney was worried about Newt and Perry and went after them taking them down, but ironically their support went to Santorum. who may turn out to be a tougher opponent because he has less baggage.
The interesting thing is Mitt spent all that money taking down Newt and to a degree Perry but it did not help him one bit in the percentage category. He has been stuck in the low 20s like forever. With Newt finishing forth I don’t expect the big attacks on him for awhile and it will give him time to make a come back. Santorum will be the one getting the full bombardment from the usual suspects.
Did you notice all of the pundits had a change in tone when they realized that Mitt wasn’t so safe after all. Of course, don’t tell Karl Rove. ;)
