I'm a latecomer to the environmental issue, which for years seemed to me like an excuse for more government regulation. But I can see that in rich societies, voters are paying less attention to economic issues and more to issues of the spirit, including the environment.

Partly because of the desperate economic situation in the country, what were once the leading institutions of conservatism are constrained.

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.

One of the reasons I've been interested in the US health care is that here is something you can do, that could lift one of the largest burdens of worry from the shoulders of tens of millions of people for whom the rest of the economy isn't working. A lot of the things that are in Obamacare that Republicans don't like were deliberately put there to force Republicans to negotiate. Republicans wouldn't negotiate, so we got Obamacare with all of the fur on it. Once it's there, of course, it's very hard to take health care benefits away from people, as the Republicans discovered.

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.

A generation ago, or two, when there were three channels, plus PBS, and when you needed - when you needed 15 million people to make a living, the media could focus on the broad country. And most people had no choice about getting political information. It was there at 6:30 whether you wanted it or not.

To balance China, the democracies will need new friends - and India with its fast-growing economy, youthful population, and democratic politics seems the obvious candidate.
