Political conventions are the stage upon which Presidential candidates need to employ one skill above all others: the art of persuasion. Jonah Berger, Professor at the Wharton School of Business, is an expert on such matters. His latest book, "The Catalyst: How to Change Anyone's Mind," argues that removing barriers is the key to changing the way people think. He speaks with Hari Sreenivasan.

The Democratic National Conventionmade history this week when Kamala Harris officially accepted the nomination to be Joe Biden’s running mate -- making her the first Black woman and the first Asian American on a major party ticket.

In 2018, at the remarkable age of 23, Tyler Mitchell became the first Black cover photographer in the 126-year history of Vogue Magazine. His cover girl? None other than Beyoncé.

On Day Three of the Democratic National Convention, the party is continuing to make a case for change. Decency and normalcy are the pitch leading up to Joe Biden’s big speech on Thursday, but the convention itself is highly unconventional: speeches via videoconference and keynotes by 17 speakers rather than just one. DNC chair Tom Perez joins the show to discuss his party's platform.

At their unconventional convention, the Democrats are sending a clear message: The stakes -- for the country and for the world -- have never been higher. John Kerry knows what it is to be a Democratic nominee battling a Republican incumbent, having faced off against President George W. Bush in 2004. He joins the program to weigh in on this year's convention and current events.

Apart from its format, the most striking feature of this Democratic National Convention is its unity. Joe Biden’s former rivals are standing up to show their support, including Sen. Cory Booker, whose own campaign for the nomination was all about reconciliation. As he prepares to speak on the final night of the convention, Sen. Booker joins the show to reflect on the stakes in this election.

Davis shares his thoughts with Hari Sreenivasan.
