I discovered in writing the biography of Bill Clinton that it is actually easier to write a biography of someone who is dead. Although you can't interview them, you have a fuller perspective on their whole life after they're gone and people are more willing to talk about them.

And that John F. Kennedy uttered the first variation of "ask not what your country can do for you" in Detroit on Labor Day in 1960. So Detroit was really central to Democratic politics United States. Every Democratic candidate would start their fall campaigns in Cadillac Square.

It is?classic Bill Clinton, sincere and deceptive at the same time, requiring a careful reading between the lines.

Well, there is something beautiful about ruins. I mean, in one sense it's not that different from going to Rome and looking at the Forum. But it's changing. It truly is. I'm optimistic but skeptical.

Detroit was an exaggeration of what was going on across the country. You could see the divisions, even within the Civil Rights Movement of that period. At the same time that Martin Luther King was talking about his dream, Malcolm X gave his most famous address in Detroit during that same period, "The Message To The Grass Roots," dismissing the notion of integration.

I want to write for history, not for the moment.

It was so crucial to the Civil Rights Movement that on June 23, 1963, Martin Luther King came to town, walked down Woodward Avenue with more than 100,000 people and delivered the first major public iteration of his "I Have A Dream" speech, two months before he did it in Washington.
