Part of the issue is populism, which is as strong on HN as anywhere else. If I said 'hey the US & other countries should move away from a presidential system to a parliamentary one, because by making choosing the leader less democratic it reduces the cult of personality', I'll get a ton of downvotes. If I said 'the US shouldn't have primaries but instead let party elites choose their candidates [the way the rest of the world operates] to reduce the cult of personality', I'd get a ton of downvotes. If I said 'hey strong political parties are actually a good thing, and candidate-centered politics where candidates can appeal directly to the voters without party elites gatekeeping out demagogues is actually really bad'- I mean, same.
The way to 'shift away from personality cult politics' is boring and technocratic, and we're in the middle of a populist, anti-elites age. Less direct elections, more appointed offices in our democracy, stronger parties, more gatekeeping & no primaries- it's exactly what we need, and it's exactly what the mood of the 2020s doesn't want right now
