So far, Mitt is winning this debate and Santorum is making a big impression too. Newt needs to clear up fannie mac big time...
From what i saw (only watched bits and pieces) i agree and think Santorum could end up gaining the most, although i don't think it'll be enough to seriously threaten either Mitt or Gingrich just yet. If he can follow it up with another good debate next time, then who knows, especially if Gingrich and Mitt keep pounding away at each other, allowing Santorum to take the high road again. As for Mitt, i don't think he cared so much about winning the debate as he did in just stopping the Newt momentum, which i think he may well have done in the opening minutes alone.
Newt needs to respond quickly and provide a much stronger answer to the peddling influence charge. His responses to Romney saying that (paraphrasing) "everyone knows what you're doing and America won't fall for it" or "this is the same kind of stuff you pulled with McCain, and it didn't work then and it won't work now" came off sounding like empty rhetoric since he didn't follow up with anything particularly convincing as far i'm concerned.
