Trump is not just unlike a Republican, he's unlike a presidential candidate. The whole elaborate presidential process is designed to screen out people like Donald Trump. And that process broke down in ways quite unlike anything in the recent experience of the United States.

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.

We live in an age of de-democratization. The number of democracies in the world has been going backwards since 2005, and even many existing democracies including in Europe have been becoming less democratic.

The habit of going to your congressman's town hall and asking questions, that's powerful in a way that shouting slogans or getting arrested is not, that is completely counterproductive.

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.

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.

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.
