Corn Copier: I knew we should have trademarked our "Cast Your Kernel" theme at the Iowa State Fair. O.K., I'm kidding. But only sort of. This is our 6th year, I believe, of having people vote with a corn kernel. They drop one into a Mason jar for the favorite candidate. HBO featured it in the movie about Barack Obama's presidential campaign. He stopped by and voted. This summer we are doing the presidential race again. In 2007, we had nearly 49,000 votes. Just stop by our booth in front of the administration building on the grand concourse. You know you want to.
