Why would Iowa go for Obama?
Bradley effect in the polling?
My understanding from talking to people from that area is that the farmers are *F*U*R*I*O*U*S* at McCain over ca orn/ethanol situation. The corn farmers are stuck with an old agreement that prevents them from growing all the corn they want - at a time when the market is high for corn - and McCain came out against a bill that would have helped them immensely.
Maybe a Freeper from Iowa could offer more details, but that is what I got from a friend whose parents are corn farmers in Iowa. These folks have never voted anything other than Republican and they refuse to vote for McCain. They are most likely going to just sit out.
Maybe because McCain came out against farm subsidies when he was running in the IA primary.
