It can't happen here: Rick Santorum's "Welcome to Obamaville" ad

With the tone of a zombie or horror trailer, and a touch of "It can't happen here," the Santorum campaign has released this "trailer."  As they say, this is  "more than a town - it's a cautionary tale!"  Notice how, at :40 seconds, Ahmadinejad's face briefly morphs into President Obama's.
