In my opinion, Gingrich has a sharp mind, a willingness to plan, and an excellent command of the spoken word. And, he is a pro-life conservative.
However, he is unelectable. Some might let a person leave his past behind. That would not happen in a presidential election, and we have decades of evidence to prove it.
He ought to be doing exactly what he was doing in the 80's, throwing inkwells and stink bombs at the deserving.
