I lived in Iowa from 1974 to 2002 except for my time in the service and helped on the Haig and Forbes campaigns, as well as for the Polk County GOP. I was with the unemployment office helping veterans and aid recipients find work.
Nothing like having lived there to know what goes on. There are so many online pundits here who were analyzing and dissecting the polls, without knowing what the real life situation is like. Of course, the polls were all very wrong and misleading.
