Maybe they were all from out of state. Who knows, nobody seems to be saying anything about talking to Iowans that were there. Come on people, post some info already.
OK. Take their numbers at face value. 800 people for six candidates, and 500 people for only one, and some of them travelled hundreds of miles to do so. Even if many were out-of-state, if you were an Iowan, wouldn't you be curious what all the fuss was about?
