Former Iowa first lady Christie Vilsack speaks at a political soapbox at the Iowa State Fair in Des Moines.
One of the country's toughest congressional races is in Iowa between Republican Rep. Steve King and the state's former first lady, Christie Vilsack.
Iowa is losing a seat in the House after the election, due to redistricting. Now ultra-conservative King is facing a more moderate electorate as he runs in the newly redrawn 4th Congressional District against a political newcomer.
