The 2016 presidential hopefuls hit the Iowa State Fair over the weekend. Along with the usual stump speeches and photo ops, they also chowed down—sort of. Donald Trump took one bite of a pork chop-on-a-stick Saturday. Jeb Bush only finished half of his deep-fried Snickers bar. It might sound silly, but the food that candidates eat on the campaign trail is more politically charged than ever. Indulging in local treats is a way to demonstrate relatability. But it’s also a liability when keeping fit is a priority.
