this actually shows in action what we have been seeing. you see mitt romney in red at 20% back on tuesday. 26%. this is just the past four days. and what you really see is the change in ron paul down and, wow, rick santorum. >> you know, it's interesting. first of all, romney, as you know, has been the most consistent. he doesn't go much below that 22%. he can't get much above the 26%. you look at santorum, though. he's probably thinking he's peaking at just the right time. some of these folks peaked a little early. i would say ron paul probably did. that's the peril of being a front-runner. once you're the front-runner, you get a different kind of treatment and you go under the magnifying glass. it's tough. >> only four days ago ron paul was the one with 29%. that shows you the brief window of time we're talking about here. back to you, wolf. >> thanks very much. it's interesting that as far as mitt romney is concerned, he's been down this road in iowa before. john king is over at the magic wall for us. he's -- he learned some lessons
