Ian Bremmer's Quick Take: I want to talk about checks and balances in the US political system. I get so many questions about this of course, because the United States today is the principal driver of geopolitical uncertainty, of global economic uncertainty. And people want to understand, is this the end of globalization? Is it the end of US democracy?

Everyone has their knobs politically turned up to 11 on everything, and that's very undifferentiated. So, how do we think about this? I want to give you a few thoughts on what is and what isn't a permanent change. What is and what isn't a serious threat and concern. Particularly big picture on the nature of the US political system.
