Foolish. Very foolish.
But I would not necessarily join you in an assumption that the foolishness was generated by a cynical and calculated triangulation to advance his chances. I think Newt simply thought he had a better plan.
He has been working on this health care matter as he points out with Heritage for over 20 years. He has formed a think tank to come up with a health care plan. I don't think he thought about disparaging Ryan's plan, I think he was simply expecting the world to acknowledge the value of the Gingrich plan.
So I see the thoughtlessness as coming out of arrogance but not calculation. I'm not sure it matters because I believe his campaign is wrecked, although he could conceivably come back, Richard Nixon style.
His chances of survival are remote but if we get no Gov. Perry or Paul Ryan he just might survive.
