You cannot blow a prediction as badly as Russ Feingold blew his. Newt described the motivations to perfection - quite frankly, there's really nothing more to say about the left wing of the Democratic Party other than what Christopher Hitchen would have said: they are frivolous.
I must confess that I am a bit twisting in the wind on Newt. I think that he gets it. I'm not convinced that he can focus the country on where it needs to go, which is devolution at home and clarity abroad. There is perhaps a Shakespearian Tragedy to be written about Newt. Act the First is the 1990s; Act the Second is the 2010s.
