Well it is only one debate and Newt better do a million times better or he might as well pack it in. He is now the only candidate to have only 1 state in his pocket. Maine is next on Saturday and not sure how that will play out but could be Romney (yuk). Then Arizona and Michigan which who knows what will happen.
There are two debates, an Arizona and Georgia one before Super Tuesday. Looks like the March 5th one was cancelled though.
