They went into the field a few hours ago and have this to say already:
Iowa poll's in the field, first respondent picked Santorum, MOE on that is +/-98%
Iowa still looks very close between Paul and Romney but Santorum's within striking distance and has all the momentum
Given the current trajectory I think there's some chance Santorum could win Iowa without ever leading in a poll
About 30% of Iowa voters saying that they've decided in the last week...and that means they can change again before Tuesday
BTW crying only works with Democratic voters, Newt clearly out of the top 3 and has upside down favorability in Iowa
