The two latest polls from Iowa in both the Democratic and Republican races are within the margin of error and don’t “agree” with on another(since they are within the margin of error the findings actually overlap). Bottom line: it’s really close in both races and you’re not going to definitively know by polls who will win in four days. What is more the actual result may be a very nondecisive win by a point or two which leaves Romney and Huckabee both bruised but unbroken. What is clear from these however is that Thompson has not made a sgnificant move. A result where he is bunched tightly with Rudy and McCain well behind the two leaders is not likley to do much for his attempt to leapfrog to South Carolina and then Florida.
