If Gingrich were to drop out, Romney would destroy Santorum in one week of negative ads. That's a fact.
How so? All of his negative ads are focused already and have been since it came to light that Santorum really did win IOWA. From that point forward Romeny has been scared crapless over Santorum stealing his thunder. You honestly think Mitt would be wasting his money giving negative ads towards Ron Paul or Newt? Either one of them has a snowball’s chance in hell of even being competitive.
