Democracy is not about protests. Democracy is about meetings.

But the thought leaders on talk radio and Fox do more than shape opinion. Backed by their own wing of the book-publishing industry and supported by think tanks that increasingly function as public-relations agencies, conservatives have built a whole alternative knowledge system, with its own facts, its own history, its own laws of economics.

Speech writers are more vulnerable to vanity than any other group of people in Washington.

Maybe it's true that people with less extreme views who are also interested in public affairs have been driven out by a marketplace that doesn't offer them anything of the tone they want to listen to.

Venezuela has gone from being a democratic country 15 years ago to being totally not a democracy today. Usually that de-democratization doesn't take the form of a heavy handed police state.

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.

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.
