"Obama will mop the floor with Santorum."
I doubt that.
The biggest knock that some have against Santorum in debates is that he's "surly" or whatever... but hey, so is Obama (just go back and watch his debates with McCain)- so they would be neutralized in this aspect. Yeah, Newt would do very well against Obama in debates- but debates aren't everything, and who knows what's going to come out of his mouth from one minute to the next during the long campaign season?
