Maybe, but at least Newt brings some substance to the debate. He may not make it past the few first primaries.
I would certainly like to see Newt with a Cabinet position in a future Republican administration, but he will never be POTUS.
Gingrich has too much baggage. I wouldn't want to see him on a repbublican ticket, the media would make mincemeat of him. He was good at getting the job done, but his personal life was an issue when the republicans impeached clinton.
