This is a time when the United States should be standing tall. There is no other leader in the world today. We shouldn't be approaching conflicts as a team sport. We either get in an we lead and we do a good job, or you don't get in at all.

And the trajectory that our debt is taking now beyond $14 trillion is going to have an impact on our currency. It goes south, and our currency's going to have an impact on our standard of living and affect every family in this country, and over time, our international competitiveness.

We're fighting an enemy that is far different than any we have got before. It's a nontraditional kind of war, and I think we need to step back, recalibrate how we go about protecting our borders and protecting our people, and resetting our position in the world.

This is the marketplace of political ideas. This is how America operates. It's a free market. It's free-wheeling. From the outside, it looks unpredictable. There's a circus-like free market.

My dream of politics all my life has been that it is the common business, that it is something we owe to each other to understand and discuss with absolute frankness.

My work has gotten more political over time, but once you start exploring food, you find you're up against economics and politics and psychology and anthropology, all of these different things you have to deal with.

The Patriot Act is ludicrous. Terrorists have proved that they are interested in total genocide, not subtle little hacks of the U.S. infrastructure, yet the government wants a blank search warrant to spy and snoop on everyone's communications.

We don't want a busybody government - a boss - that butts into our lives every chance it gets to tell us how to work, how to play, where to live and on and on.
