this is just totally incorrect. the field is too big at this point to unify behind a single candidate. romney can’t get above 20-25%. other than the bonkerz paulbots, everything else is the anti-romney vote.
and besides, iowa is just irrelevant. a caucus is a mob. it’s a ridiculous way to pick a presidential nominee.
Iowa caucuses pick delegates to county conventions and begin compiling a party platform. No delegates are committed to a candidate. All the angst is over a secret, non-binding presidential preference vote where attendees write any name they want on a blank sheet of paper. Iowa doesn’t choose delegates to the national convention (which chooses the nominee) until June.
