This year’s Republican National Convention was Donald Trump’s third as the party’s nominee, but it was the first that felt like a full expression of a G.O.P. that has fully fallen in line with Trumpism. And the mood was jubilant. Speakers even made efforts to reach out to unions, Black voters and immigrants — imagining a big-tent Republican Party that could be far more formidable at the ballot box. But if the Democrats were running a strong candidate right now, no Democrat would look at that convention with fear. In this conversation, moderated by the show’s senior editor, Claire Gordon, we dissect the themes and undercurrents of the convention and what they might signal about a Republican Party in the midst of change. We discuss how the party is messaging about race, immigration and populism; what JD Vance believes and represents for the party; what all this means for a Democratic Party that is divided about President Biden’s candidacy; and more.
