We look at the state of the Republican Party after Republican Florida Governor Ron DeSantis’s announcement Sunday that he has suspended his presidential campaign and endorsed Donald Trump to be the Republican Party’s 2024 nominee, making it a two-person race between Trump and former South Carolina Governor Nikki Haley. With the pivotal New Hampshire primary on Tuesday, we speak with author Rick Perlstein, a historian of the modern conservative movement, who describes Trump’s iron grip on the Republican Party as “American fascism.” He says regardless of how many votes Trump gets, the real question is how his extremist supporters will respond. “The horse race doesn’t matter if the guys in the MAGA hats blow up the track,” says Perlstein.
