With regard to the more moderates, I have spent 20 years as a United States Marine. I'm a little more realistic when it comes to some of these foreign policy, defense policy issues, some of the things we do overseas. And so I really feel like I can connect to the more moderates.

From this experience we have learned that in a big party it is important to have the necessary and often controversial discussions on policy issues such as the health system while in opposition.

I get along very well with Paul Ryan personally. We have very deep differences on policy issues. But we express them civilly.

I believe that when it comes to major foreign policy issues, many prefer to have black people seen and not heard.

I can give substantive advice to the administration, the president's campaign, or any campaign that would ask for it. And, of course, when I speak I can talk about my views on policy and I have been supportive of the president's policy on leading foreign-policy issues.

I love and always have loved policy issues and trying to have an impact on the issues that are out there. I cherish my years in government. I have loved my participation at CNN, at Current; writing; teaching. Where I will go next, I will have to sort out.

There are some very real areas where working together is critical, whether it's talking about public policy issues, enforcement, or how to work together to facilitate new business opportunities. The RIAA has gotten much more involved in that.

I have learned as much in the last three years as in any other comparable period of my life, but with an added realisation of how little over a half century of study one has in fact managed to learn of the whole range of economic policy issues.

There is a big divergence between views on a variety of policy issues from fiscal stimulus to financial regulation. It's my hope and my ambition for the economics profession that as we advance our knowledge, that those discussions will narrow in their focus, and that it will help to have more prudent policy-making down the road.
