In a funny way, the kooky drug taking liberal Joe Rogan could actually claim to be Rush’s successor. He’s the one who can boast a bigger audience than the mainstream media, he’s the one who can bring an issue into the minds of the common people just by mentioning it on his show, and he’s the biggest target of the left to be cancelled, but also is essentially uncancelable.
I think Steven Crowder comes closest to Rush.
