Gingrich wants to GUT the federal government. Check his website.
But I think Gingrich could have really fired back and launched some spot-on points about things like the trillion-dollar deficit, less, not more, government programs, etc. I think he probably missed his queue right at the starting gate when Blitzer baited him into a swipe at Romney. In the past, Gingrich has successfully called the moderator on that kind of stuff. (He did later but not as effective.)
I'm actually wondering if Gingrich's handlers influenced him the last couple of debates to play a "prevent defense" (almost always fails) instead of putting on a full-court press (i.e. defensively keep from losing instead of offensively going all out for the win).
Hope for the best.
