The pro-GOP U.S. Chamber of Commerce has usually produced decent ads starring a red state-friendly celebrity. But this one has to be one of the stupidest commercials I've seen in a very long time. It stars a chicken and hits Democratic Senate candidate Bruce Braley with something called "the chicken dance." It's hard to describe it: This is an ad you just have to see to believe. Of course, when you're winning, you can afford to air terrible ads like this, and win they did.
