Democratic candidates at the Iowa Exhibition

More than 20 of the Democratic presidential candidates are hitting the Iowa State Fair this week, where they’ll talk with voters and sample the famous fair food. They’ll also be addressing fairgoers at “The Soapbox,” the Des Moines Register’s stage at the fair. The contenders will each have 20 minutes to sell their candidacies to the voters in Iowa, by tradition the first nation to hold a nominating contest.
