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.
The drought is beginning to really sink its teeth into the Midwest. More than three-quarters of the nation's corn acres are in a drought zone. In Iowa, Illinois and Indiana, corn crops are burning up and its causing commodity prices to shoot up. Suburban residents are paying to water their lawns, but it isn't doing much good.
