Yes, I'd vote for Newt. He has a vision I mostly agree with, he has a detailed program and he is a proven leader who can actually accomplish things.
If I thought that Newt would survive the MSM onslaught he'd suffer if he was the nominee, I'd be behind him. But I don't think he can politically survive the "Gingrich who stole Christmas" stories that will become a daily fixture of the MSM until Election Day.
He's all of that and much more. He has a great historical understanding and perspective, a knowledge of economics and political science none of the other candidates have.
Having said that, he is completely unelectable under almost any scenario. But if he enters, I hope it is early enough to impact the debate and educate the candidates more. In that respect, his baggage should not be a factor, and the quality of the debates by the candidates will be ramped up substantially with Newt in the fray.
