Hillary is old school tax and spend. It won't work today. Ryan is young and fresh, and up with what's going on in the "Now".
That scratches the economy, but Hilary is SoS. What if that situation in the Middle East blows up? What if Israel attacks Iran? Israel says it will last a month. Where will our SoS be? She ‘ll be campaigning. To be sure obama will try to use that. I can see him say: “we got us a nuclear CRISIS in the ME and we need experienced foreign policy people in the WH.” It makes me sick to think of it. Wag the dog.
