The fear is that Newt Gingrich can not throw a targeted punch at Mitt Romney, that he is only capable of a crazy melee.
Today, Gingrich is proving his critics wrong.
One of the biggest knocks on Romney is his timidity in the face of Barack Obama. He won't use the word "socialist," etc. He won't be bold with his own plans, etc. Well, Gingrich is going straight to that weakness and I think it works.
By the way, this is also the perfect way to show why the other guy can't beat Obama while keeping the focus on Obama.
