We [the United States] are the world's only superpower right now, so everyone notices every bit of what we do or don't do.

We cannot be spun, or at least we'd like to think that we cannot be. And the presidents who are trying to - too overtly to try to say, here is what you historians and what you later Americans should think of my presidency, 30 or 40 years later, they look silly.

The founders were very worried that if parties developed in America, you might have something like the modern Italian system, where you have 20 different parties that divide Congress and the country and can't govern.

As you look back in history, we [the United States] have done wonderful things, the Marshal Plan is the most obvious. After World War II, we spent billions of dollars to rebuild Europe or at least part of Europe after the devastation of World War II. We did it out of charity, but we also did it to keep the Russians from getting deeply into Europe.

What if we had a culture that prevented these presidents from being courageous? And I worry now that we have a system that makes it very hard to choose people who would make the same courage choice as our great presidents. And I guess what I would say is, in this next campaign, take a look at the people who are running. If they don't remind you of the great presidents, do not vote for them.

Lincoln was able to say, you know, "It will make me very unhappy if I lose the presidency, but I'm committed to larger things." If you look at candidates and say this is someone who can be happy to go back to their family or they have larger convictions. Franklin Roosevelt jeopardized his presidency by telling Americans in 1940, "We might have to fight Hitler." He loved being president, but he loved defending freedom more.

Then you get to the last half of the 20th century, Americans are getting very skeptical about their leaders and their institutions, and another place that is affected is parties and conventions.
