The thing with Trump, like Boris Johnson in UK, is that they both were able to jump the queue as it were and get the best preemptive treatment before their cases developed. Sadly that cannot be available to everyone, but I fear their high profile recoveries downplayed some people's sense of how serious the virus can be, unless they have first or second hand experience of it.
From the UK - while I'm no doubt in your ballpark of the argument, it's only fair (to the truth, whatever that is these days) to point out that the British PM did not receive any preferential treatment, in fact (as so often in this crisis) was slow off the mark to get himself into a hospital ward. Once there, he had oxygen but, as far as we know, no special drugs (unlike DT). He went back to work far too early in the opinion of some, who felt he may have suffered some short term memory loss. Secondly, BJ's near-death experience with Covid actually sharpened the UK population's understanding of it, not the reverse. And I'm not a fan (of either man). Since then, the mostly very aware UK population has been rather let down by the indecisiveness of its leaders (in England, at least).... but you certainly wouldn't get a carefree election rally happening here.
