Obama stunned the nation in January 2008 when he won the Iowa primary -- a win that pushed him into the forefront of the Democratic presidential nomination race. Here, he sits with Hunter Hesler (left), of Webster City, Iowa, and Kyle Leksell, of Blairsburg, Iowa before speaking at a potluck picnic in Iowa in June 2007. File photo / Associated Press
