If there’s one state where politics never turns off, it’s Iowa. And while preparations for the next Iowa Caucus seem to start the day the current Caucus ends, there is, perhaps, a more interesting new development on the Iowa horizon – for the first time since 1984, the state is about to elect a new Senator.With Sen. Tom Harkin’s decision not to run for a sixth term, Iowa is suddenly another key player in the biggest theme of Midterm 2014 – the battle for U.S. Senate control. How is the state leaning? Could the seat actually be up for grabs? And who will represent Republicans: A pig-castrating, gun-range visiting state senator or a former Fortune 500 CEO who has returned to his home state to try and steal a victory?Few follow Iowa politics more closely than Radio Iowa News Director Kay Henderson, who, as her bio points out, was born on Election Day.
