FILE - In this Oct. 21, 2013, photo, Rep. Bruce Braley, D-Iowa, talks with area farmers as he tours the East Central Iowa Co-Op in Cedar Falls, Iowa. You might think this year's candidates had learned from Barack Obama's comments about bitter people who "cling to guns or religion." Or perhaps from Mitt Romney's apparent dismissal of the 47 percent of Americans who don't pay federal income taxes. Braley apologized after describing six-term GOP Sen. Chuck Grassley as "a farmer from Iowa who never went to law school, never practiced law." (AP Photo/Charlie Neibergall)
