I don’t think really it’s old fans from the 80s & 90s - it’s just too much of a volte-face from the mindset that attracted people to his music back then. I think some old fans have become apologists for him, but the new ones are just gravitating to the liberal baiting outbursts. I don’t even get the sense they’re that fussed about the (underwhelming) music.
It’s horrible watching this decline. All the while his face appears to be getting steadily younger - that portrait in the attic must be looking pretty ugly by now.
