Jon Lieber, Eurasia Group's head of research and managing director for the firm's coverage of United States political and policy developments, shares his perspective on US politics from the Democratic National Convention in Chicago.

What we're watching in US Politics: The Democratic National Convention Day 2, where former President Barack Obama is set to speak and rally support for Kamala Harris ahead of her Thursday appearance.

We are here in Chicago on day two of the Democratic National Convention, where tonight, former President Barack Obama is set to speak. Yesterday's, opening day at the convention was all about turning the page on the old guard of the Democratic Party, with Hillary Clinton giving a speech and Joe Biden giving a strong endorsement of Kamala Harris. And today is all about handing that off to her, with Obama, who's considered the Democrat's best speech giver and one of the most exciting figures that unifies the party set to speak tonight in order to send a message of Democratic unity rallying around a Harris. Kind of a quieter day here in Chicago. There are some protests going on related to Gaza that aren't really affecting the proceedings at all.
