Doesn't matter. Gingrich would absolutely wipe the floor with him. Most of us here would. That we have to worry about the debating skills of some of our candidates is not a reflection of how hard it is. It's a reflection of just how pathetic politics and politicians have become.
Too bad debating is so highly favored. Most decisions a president makes are not split second. How about having various people present questions a few days ahead of time so the candidates can think about them a bit more deeply and present a well-thought response.
