If you mean book sales I'm not so sure it's that simple. He has dough. He has smarts. But his political compass is broken.
I admit that money *could* be part of it but if I were to be that cynical I'd be more tempted to say that he sees the writing on the wall, has decided that the left will continue in power and has cast his lot in with them so as to retain power himself. The money would come later as a payback for undermining conservatives.
But this is a *very* cynical view and I'm not prepared to dump that on Newt just yet.
I'm still wondering why he's doing it...his stated arguments don't wash.
He recently converted, he has sold out his conservative values. He started with global warming, i’ll bet he holds stock in green companies, and yes I am that cynical.
