Jon Lieber, who leads Eurasia Group's coverage of political and policy developments in Washington, offers insights on the latest in US politics:

What has been most revealing to you about the Amy Coney Barrett hearing so far?

Well, what was interesting about them to me was how nakedly political they are. Normally, you have at least the pretense of probing the justice's judicial philosophy, trying to figure out where they stand relative on the political spectrum. But here, you know, the Republicans know they have a vote, so it's largely been cheerleading. And the Democrats have been running what looks like a political campaign, asking questions about the Affordable Care Act, bringing up constituent stories of people who are going to be affected should the Supreme Court knock it down in a way that just is really unusual for Supreme Court. I think that just reflects the polarization of the court and political polarization more generally.
