At this event, held before an enthusiastic crowd of 2,500 at the Iowa State Fairgrounds, Obama reminded the crowd that Romney said “corporations are people,” while stumping in Iowa last August during the Republican primary. The president said there may be value in Romney’s experience in corporate buyouts, “but it’s not in the White House.”

He also noted that the former governor doesn’t talk about his record in Massachusetts.

Speaking directly to Iowans, Obama used local lingo to slam Romney: “Governor Romney came to Des Moines last week and warned of a prairie fire of debt,” he said. “But he left out some facts. His speech was more like a cow pie of distortion.”
