Ian Bremmer shares his perspective on global politics this week:

We'll start in Brazil. Will Lula run for president and seriously challenge Bolsonaro?

And the answer is, it increasingly looks that way. The Supreme Court threw out former President Lula's former conviction, saying they didn't have jurisdiction. And the court that he was actually charged, court members were surprised by this. Lula's own PT party surprised by this. It means a couple of things. One, he's much more likely to run. He's extremely popular on the left. His PT party has about 20% approval in the country. And that means that between Bolsonaro, the president, and Lula on the left, there's very little room in the center. This is going to be an incredibly contentious and polarized election, much more so than in the United States, even this past November.
