How many people voted for that "one individual causing chaos" again? 70 million? He's also backed by billionaires and an administration that seems to be just as unhinged. It's not one person causing chaos, it's a whole country with its violent culture. The scale changed slightly, but it's also nothing new.
This. There are really two explanations here. Either the US hasn't been a democracy in the first place. Or the majority of the US voters prefer autocratic amoral psychopaths running their country.
