Amid plates of sliced pork, statement-making leather ensembles and piles of political T-shirts, eight Republican presidential hopefuls descended on Iowa to pitch themselves to voters and, in Mike Pence’s case, hop on a motorcycle. The former vice president and Florida Gov. Ron DeSantis were among the White House contenders appearing at a rally at the state fairgrounds near Des Moines hosted by U.S. Sen. Joni Ernst. Her annual political event, the “Roast and Ride” — a combination barbecue-rally and motorcycle ride — kicks off a busy summer campaign season heading into the state’s first-in-the-nation caucuses early next year.
