I'm going to make a prediction - Obama and Edwards are going to lead this Iowa caucus thing. Not sure of the order, but I'm leaning towards Edwards coming out on top.
On the Republican side, I'm thinking Huckabee (yuck!), Richardson, and Thompson. Not necessarily in that order. I distrust polls for conservative voters; we tend to think "none of your business" when asked what we will do.
I'm leaning Thompson. He seems both sensible and electable.
