Santorum's apocalypse two years from now

It was a tough week for Rick Santorum, suggesting that it would be better to elect Barack Obama than an "Etch-A-Sketch" Republican like Mitt Romney and then walking it back.

Now he's out with an over-the-top apocalyptic web video in the vein of every zombie movie ever made, depicting a stark world with vacant streets, boarded up buildings, and empty children's swings -- all caused by a president's "failed policies" particularly toward Iran.

The video even flashes an image of Mahmoud Ahmadinejad and President Obama.

Santorum spokesman Hogan Gidley called it "absurd" to think the campaign is comparing President Obama with the Iranian leader.

But that's not the only eyebrow raising aspect of this ad, titled "ObamaVille." It is supposed to take place in a "small American town two years from now if Obama is re-elected." At one point, a man is pressing a gas nozzle against his head. At another point an imagine of a man in an orange jump suit is quickly followed by one of a baby in a crib.

"If Ahmadinejad gets a nuclear weapon, then we're obviously going to deal with the fallout and coverage of that," Gidley said defending the ad. "All we're going to be seeing is images of him and the president. We were trying to illustrate that."

He said it is the first in a series of ObamaVille ads. It's the work of senior strategist John Brabender.
