In the first ad in her Senate campaign to replace Iowa's retiring Tom Harkin, Joni Ernst - "Mother, Soldier, Conservative" - boasts she grew up castrating hogs on an Iowa farm "so when I get to Washington, I'll know how to cut pork." She's one of five GOP candidates. She's endorsed by Mitt Romney. She's wearing the biggest, weirdest, grimmest zombie smile you ever did see. As far as we can tell, this is a real ad. God bless our participatory democracy.
