Hillary Clinton's such a classic Democratic political figure and believes so much in institutions and in gradualism in the old way of reaching compromises with the opposition in the back rooms. That's what she did in Congress. It's what I imagine she'll try to do in the White House.

What goes on in a person's head, what impels them to a political choice, it's a pretty complicated question.

It used to be that the working class, broadly speaking - Americans who worked with their hands, who worked in factories, who were not in management - were an interest group, a political interest group. And their main spokespersons were the Democrats. Their platform was the Democratic Party. And that began to change after the 1960s. Not for black or other working class Americans, but for white working class.

We all know who Donald Trump's talking to.

When Donald Trump in one speech said I love the poorly educated - which was a remarkable thing to say - he was saying those are my people.

The literature of the Spanish Civil War is also important to me. Above all George Orwell's "Homage to Catalonia" as well as the writing of John Dos Passos and Ernest Hemingway. They worked on a film together in Spain during that war, which ended their friendship.

I do think Donald Trump would be a catastrophic turn in American history.
