I'm probably in the minority on FR, but I agree with you and rank Newt below Romney. They're both RINO sellouts who know how to talk conservative but suck up to liberals and would drive over their own grandma to get votes. The main difference is Romney is much more personable and has far less scandals. Voters can't stand Newt regardless of how effective he is at debating. Pretty much if we nominate Newt, we guarantee Obama a second term.
I’m not sure any more where to rank them.
As for electability they both have issues.
Romney is very arrogant too but hides it better. Notice how he smirks at the candidate standing next to him at every debate. He always looks like he’s holding in a scoff.
Gingrich at least was never an outright liberal like Romney. So I like him better, I guess. ;/ Blah.
