They Lost to Trump. Now They’re All In.

On the second day of the Republican National Convention, a collection of Donald Trump’s former challengers took the stage. There were people who ran against him in 2016 — like Ted Cruz, Ben Carson and Marco Rubio. And people who just challenged him this year — Nikki Haley, Ron DeSantis and Vivek Ramaswamy. No matter how fervently, or recently, they had criticized him, all voiced their support for him and emphasized a message of unity. For analysis of Night 2 of the R.N.C., and this parade of Trump rivals turned boosters, Astead is joined by his Times Audio colleague Michael Barbaro, host of “The Daily.”
