Romney should be incredibly popular in his own party since he has not faced the negative ads others have faced. But Romney is not popular...his support in the GOP has been stuck at 25% since, oh, about 2006. Imagine what the result in Iowa would have been if if Romney faced the barrage of negative commercials that Newt Gingrich faced?
Romney's negative attacks, or rather those of Restore Our Future, which is not at all connected to Romney's campaign (yeah, right), might have awakened a bear in Iowa. Post-Iowa Gingrich is vowing to end Romney's free pass and begin hitting him with negative advertising defining him as the unprincipled flip-flopper who thinks he can buy the nomination. While Gingrich may have lost the nomination in Iowa, he can do the Republican Party a favor by exposing Romney for the person he is. It is about damned time.
