Campaign snapshots: Rick Perry and President Obama board the bus

Rick Perry ate a vegetarian corn dog on a stick, an egg on a stick and a pork chop on a stick while campaigning at the Iowa State Fair. But the strangest moment came when he posed with a cardboard cutout of a soldier in Afghanistan. The legs under the cutout are a nice touch.

Meanwhile, President Obama seemed to be reacting to the Minnesota heat and the political heat as he criticized the GOP presidential field.
