The system has evolved to protect parties from people like Donald Trump. It really is true that people without well-established public records, without proven capability in public service, without tested beliefs and at least apparently under the influence of a foreign power, such people are screened out by major parties.

We all work for media, we all make mistakes all the time. That's inevitable. What the difference between a responsible journalistic institution is, does it care whether it makes mistakes or not? And does it correct them?

Elites are inevitable in politics. That is how politics is going to work. The question is, are your elites responsible, public-spirited? Do they think about the interests of others, not just themselves? And the story of Western politics since the beginning of the century is that as elites become more separated, more selfish, as they leave behind their populations and don't think about them, they become discredited. And the people look for alternatives. But the alternative is worse. Those rules of the game protect us all. And they are more precious than almost any political outcome.

America under 30 is a more non-whites place than America over 60. And we know that non-whites and whites vote differently.

One of the great drivers of the alienation that has made Donald Trump possible is that the growth in the American economy has been weak. In the decade from 2005 to 2015, there was not one year when the US hit three per cent growth. And to the extent there's been growth, virtually all of it has been collected by the top 10 per cent of the population. Obviously, if we knew how to make growth faster, we would. We don't. And it's very difficult to make growth more broadly shared. Because it's not just the US that has this problem.

What I say is I am somebody who cares about conservative ideas. I want to see them implemented in governance.

I always believed as a speechwriter that if you could persuade the president to commit himself to certain words, he would feel himself committed to the ideas that underlay those words. And the big shock to me has been that although the president said the words, he just did not absorb the ideas. And that is the root of, maybe, everything.
