Dana Milbank is not one of the beltway pundits that admires Paul Ryan's "seriousness". He was at the Iowa State Fair to report on Ryan's first effort on his own to stir up the crowd. He was met by hecklers as well as by Romney supporters. Its hard to stack the crowd with supporters at an event like the state fair. Ryan's efforts to convince the crowd that folks like him from Wisconsin, are just like folks from Iowa, was not a big hit. The simple folk in Iowa seem to have a pretty good idea about Ryan's economic policies.
They pulled Ryan out of an event in Florida to send him to a more friendly atmosphere in Iowa. They dislike what Ryan wants to do with Social Security and Medicare as much in Iowa as they do in Florida.
