"You scolded Mitt Romney, his friends who are running this Super PAC that has funded that, and you said of Mitt Romney, 'Someone who will lie to you to get to be president will lie to you when they are president. I have to ask you, are you calling Mitt Romney a liar?"

I don't think he's being candid and that will be a major issue. From here on out from the rest of this campaign, the country has to decide: Do you really want a Massachusetts moderate who won't level with you to run against Barack Obama who, frankly, will just tear him apart? He will not survive against the Obama machine."

I would support a Republican candidate against Barack Obama because I think Barack Obama is tearing the country apart.
So Newt Gingrich thinks Mitt Romney is a dissembling robot who cannot be trusted, but his name isn't Barack Obama, so he'll get Newt's vote. With endorsements like that, Romney doesn't need opponents.
