Yes, that is true. Unfortunately, as I see it, this tragedy once again reinforces my belief that many humans can be so stupid and ideologically blinded that they forego any rationality and connection to reality. No rational person could ever want Trump to be their candidate unless they had something to gain from it. Almost no one has anything to gain from a potential second term except some schemers and ultra rich.
This seems to be an inherent flaw in present-day democracies. I am from Germany, and we are experiencing the same thing with an alt-right party that is set to win the most votes in the 2025 election, with an ultra conservative party likely being second (or maybe their positions will be flipped, it does not matter effectively). Germany, just like the U.S., is on the cusp of losing freedom and democracy. And once it’s gone, it will be a hard fight to get it back.
Anyway, for future attempts at democracies, I think we need even stronger constitutions that make such stances and policies like the ones from the Republican party illegal, and we need institutions that are willing to enforce such constitutions. Furthermore, rigorous civic education should be implemented so that the populace becomes less susceptible to populism. Finally, in order to qualify for the privilege to vote, would-be voters should pass some kind of (equity-compatible) test every election year that assesses whether they still possess critical and rational thinking capabilities.
But I imagine that the most effective measure would be to treat conservatism and related ideologies the way that fascism / national socialism is treated in Germany. Exclude radical conservative and nazi opinions from the right to freedom of expression and make advocation for them punishable. Furthermore, outlaw all political parties along those ideological lines.
These measures are not pretty, but as it stands today, much of the votership in Western democracies is just not qualified for partaking in national elections.
