I've become a sortof fan of Rogan's podcast in the last year. But I only listen to episodes here and there, it entirely depends on the guest.
Rogan's not a bad interviewer, but he's also not remotely funny (which I've realised might actually be an asset for his interviewing technique) and a lot of his guests are dodgy and/or annoying.
Rogan is obviously disturbed by being seen as 'alt-right adjacent' and I think he's recently been trying to address this by having more left-wing people on.
I'm guessing Bernie came on because his buddy Cornell West was on recently (one of the best JRE episodes ever, although the one with Alex Jones recently was up there too tbh):
