Person outside the USA here (reasonable, hopefully).

First off, it is too simplistic to try and categorize a political regime as "ok" or "not ok". A political regime, the problematics of a large country, and and a huge voting base of people like the US population, are an extremely complex phenomenon. One will not reach useful insights by labeling a regime as "not OK" and its voters as unintelligent or evil (I am not saying you are doing so, but lots of people do).

Talking about reasonable people: for reasonable people, the Trump regime, and any regime for that matter, is a mixed bag of things to like and dislike, to weigh and trade off. For sure, for each reasonable person the scales will tip in different directions. But for a reasonable voter this not a sports game where one roots for their team just because it's their team.

For many reasonable voters Trump is not "ok" or maybe even "good", but he still responds to some of their pressing priorities and concerns enough that he merits voting for. I personally voted for politicians in my country that I disliked deeply, but I'd done the calculus and concluded that the alternatives are worse. Similarly, you shouldn't conclude that the electorate of Trump predominantly loves him. You hear mostly from the loud MAGA crowd, but they do not decide.

What are the concerns and priorities that may force a reasonable person to hold their nose and vote for someone like Trump? I wouldn't like to engage in a political debate here, so I will keep things meta. But as an outsider I can see political and social trends of the last decade that are quite prominent, rather sudden, pretty radical from my vantage point, and concerning to conceivably reasonable voters enough to tip the scale, even if you or I may not really align with them specifically.
