I don't see the Trump fandom clinging onto him forever. Assuming he doesn't run again in 2024 (Which is a very real possibility now that I say it aloud but who knows what the next 4 years will be like), his supporter base will probably cling onto some new nationalist strongman figure who is either running for or is in office. I don't see Trump's supporter base actually liking the man himself (He's a coastal elite hollywood tv show star or whatever they're on about), but more that he enables his supporters to project whatever xenophobic, racist, misogynist, nationalist etc. views onto him. As soon as Trump leaves his political career behind him, they'll remember him fondly but find some new nutter to cling on to
