That's easy. Only stupid people took this idiot seriously. The problem is that the US has too many idiots.

Probably too distracted by culture wars and other single issue pet peeves to pay attention to the whole picture. My coworker says he agrees with most of what Trump says but is extremist on others. I was like, it's part and parcel what did you expect? A friend supported Trump for his non-interventionist foreign policy, which may be true on Trump's first term, but not so much anymore on his second term. I haven't spoken to him in a long time but I reckon he may be regretting supporting Trump.

What I notice about Trump supporters or those who sympathises with him, is that they don't really talk about economics or how his bill guts major public investments and agencies, and give more tax cuts to the rich. It is more often on culture wars, or even Epstein files (not dismissing the Epstein files but the Republican economic policies will have more severe consequences to Americans in generations to come and should be talked about more).

A lot of people supporting an ideology or a politician is being in our own social bubble. In my social media feed, I see only anti-Trump content. For others, they see pro-Trump. We've became more polarised since the Second World War because of the advent of new modes of communications. In the 20th century, TV and radio were the social media that polarises the society Even if Trump did some good things (remember that he said Hitler did some good things, and yes, Hitler may well have) but the problem with demagogues is that they bait and switch. You can't ignore the genocidal intent of the person simply because he or she gave you free healthcare.

That's the idea.
