New Perry ad attacks everyone but Romney

A new ad out by the Rick Perry campaign targets each of his primary competitors except Mitt Romney. It doesn't call out Jon Huntsman either, but he's polling dead last nationally.

"The fox guarding the hen house is like asking a congressman to fix Washington. Bad idea," the ad begins as images of Michele Bachmann, Rick Santorum, Ron Paul and Newt Gingrich are shown.

Granted, both Perry and Romney have served as governors of states, so he couldn't really tie that in, but it's weird that his campaign would spend money attacking candidates polling behind him and not mention one word about the frontrunner.
