Why Is/Was Trump So Popular

He’s done comparable things on rare occasions when the heat gets too high. Usually he goes on to immediately undercut himself by letting his true feelings out shortly afterwards.

In any event, compared to most politicians he’s a lot more authentic.

Right. Suppose a politician was as unfiltered as Trump but wasn’t also a corrupt and amoral idiot with serious mental issues, they might do even better than Trump.

OTOH, it’s possible that the only reason Trump was/is as unfiltered as he is is due to his mental issues. Because the weight of virtually unanimous conventional wisdom saying you absolutely can’t do that is very strong. Trump is in his own mind the smartest man in the world and biggest expert on every conceivable issue, so he’s confident enough to think that all political experts are wrong and only he himself has it right. Normal people can’t do that.

As to the issue itself, it’s an example of a point I’ve previously made here WRT Trump and his appeal, which is that sometimes the total is very different than the sum of the parts.
