Obviously, Donald Trump won't be impeached or removed so long as the Republicans hold even one House of Congress. And even should they lose both in November of 2018, launching an impeachment - as the Republicans discovered with Bill Clinton - is very dangerous to the impeaching party. Unless you have a highly credible set of extremely damning facts, you turn a constitutional crisis into a political crisis. You rally potential supporters of the impeached president to him. You make his base bigger. So I imagine that he is likely to serve out the full term.

The thing that sustains a strong Fox network is the thing that undermines a strong Republican party.

You've worked hard all your life. You've paid Medicare taxes for almost 30 years. But under the Republican plan, Medicare won't be there for you. Instead of Medicare as it exists now, under the Republican plan you'll get a voucher that will pay as little as half your Medicare costs when you turn 65—and as little as a quarter in your 80s. And all so that millionaires and billionaires can have a huge tax cut.

I have a range of scenarios. One of them is a chaos, that what could happen is Congress does step up a little bit and the administration is paralyzed. And we go through all kinds of constitutional crises, impeachment or the 25th Amendment removal process. Another frightening scenario is Donald Trump is steering his way to a series of international confrontations at the same time as he's appeasing Russia.

Democracy requires you to learn how to lose as well as how to exercise power when you win. And that requires restraint all around. One of the reasons it works is because when you win you don't do things that are so upsetting to the losers that they feel like they have less, they have more to gain by turning over the system.

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?

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.
