Santorum couldn’t get his bearings...trying hard to give a right answer but not finding his footing to do so. Wasn’t about to knock Newt but fiddling for words how to make himself look good.
I kinda thought Rick actually wanted to go further against Rick, hesitated, and thought better of going to far, so he stuck with sputtering about charactor issues. Nevermind that it is the charactor of Marianne the Vicious that is in question in 2011. Newt has overcome his already.
