We all have more at stake in the rules of the game than we do in the outcomes of the game. When that changes, that's when you begin to lose democracy.

Reagan survived the Iran-Contra scandal because the elements of it that were illegal (aiding anti-communist Nicaraguans) were popular and the things that were unpopular (arming the Iranians) were quite legal.

Normally what happens in a new presidency is the president has a big agenda, and Congress is full of people with human weaknesses. And so the president indulges the human weaknesses of members of Congress in order to pass his agenda. This time it's the other way around. Donald Trump does not have much of an agenda. Congress burns with this intense Republican agenda and so does Congress that has to put up with the human weaknesses of the president in order to get a signature on the things it desperately wants to pass.

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.

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.

Canada has a real civil service, which the United States doesn't have, an independent civil service. Canada also has a stronger federal system.

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.
