Ian Bremmer shares his insights on global politics this week on World In :60.

What do you expect from the first Trump-Biden debate?

Well, I'm going to be watching it. I am a little surprised it's happening, that they agreed on the rules which are more favorable to Biden and to so-called normal politicians. But, you know, we'll see. I think there's a lot more downside for Biden precisely because his age is perceived to be so much more of a problem. The State of the Union, he did very well. But this is a live-fire exercise. It's not a set piece. And so in that regard, there's more ways you can go badly. Having said that, if he's able to stand his ground, and if Trump seems like he's slobbing more, this is a lot more about how they appear than what they actually say. You hate to say that something is important as US presidential race, but of course, that is a lot of what American politics, especially the elections, are about.
