On today’s episode of Hear Me Out… folie à deux (again).

A few weeks ago, Frank Buckley joined us to argue that Trump voters aren’t delusional. And a lot of you disagreed.

One of you, though, turned out to be an expert in the nature of delusion. So who better to join us, and make the case that we got it wrong?

Barry Mauer, a Hear Me Out listener and associate professor at the University of Central Florida, joins us to argue that the pro-Trump movement isn’t just delusional — it’s dangerous, it’s a cult, and it has to be called what it is.
