Your democracy has consistently voted senile 75 year olds for 3-elections now
The current president - who Americans voted for twice - is heavily accused of being a pedophile and has reneged on every one of his poll promise
Really not the best advertisement for democracy
To be fair, it really has been the structurally anti-democratic elements in the American system that enabled Trump to come to power in the first place, and that have allowed the GOP to remain competitive nationally for quite a long time, despite being a minority party
The US badly needs to reform these elements, but it's those elements that really make reform nearly impossible at this point.
Electoral college reform, gerrymandering reform, increasing the size of the house or some kind of proportional representation, etc
The difference is that there was (at least an illusion of) choice. Nobody said that it is a perfect system. And Trump will be gone in 3 years, while Putin and Xi will stay in power until their death.
