It would be a disaster for Mittens. Believe me, he does not even have a contingency that assumes a loss there. If this happens expect ramped up talk of a "brokered convention" with La Raza assclown Jeb Bush pimped on us.
You really think Romney will let Santorum defeat him?
Unless the 2 really have a pact to remove Gingrich, Romney will fire at Santorum mercilessly.
Granted the media and the GOP E might want Santorum to keep Gingrich in check, but if they help to creat a Santorum monster to threaten their chosen Romney, how will they get Romney nominated?
