WATCH: Is Romney Slinging Poo At Santorum In New Smear Ad?

With polls showing Mitt Romney and Rick Santorum in a dead heat for the GOP candidacy, you could easily predict that the Republican presidential race was going to get a little nasty. We didn’t know it’d get this kind of nasty, though.

A new ad from Santorum’s campaign shows Romney “slinging mud” at a life-size cardboard cut-out of Slick Rick. Doesn’t that mud look awfully, um, fecal? Is Santorum aware of the implications of this smear ad?

Now that they both have scatological Google problems, maybe we should expect an all-out poo war.
