Thought that was a feature and not a bug for his base?
Biden had a base?
2020 was 100% that just enough people were scared shitless of Trump round 2 that they voted against him. Top of the scared shitless list were Democratic power brokers who pushed for Biden with endorsements and scripted or not, some timely drop outs and timely non-dropouts, because they felt the best chance against crazy Donald was milquetoast Joe.
I think current events are showing that to be a mediocre strategy. The fact it works really shines a light on how weak Trump is.
