There's definitely a divide in his fans. There are the old Opie & Anthony people who mostly just listened for comedy. The pandemic changed a lot, Rogan started with his vaccine stuff and that attracted a lot of MAGA types.

Comedy in general has taken a right-wing shift. During the COVID lockdowns touring comedians could only perform in areas that didn't have extreme restrictions, now comedians like Bill Burr and Tom Segura are incredibly popular with conservatives. I saw Bill a couple of years ago and he was making jokes about about conservatives and a large section of the crowd was unironically agreeing with his dumb caricatures.
