They base this assertion in two principles that any democracy should fulfill:
1) Power separation. 2) Representativity.
I can see that you don't agree with this, but what country has a better system then?
The mere fact that most people feel that way shows, to me, that the system works. Compare that to e.g. France where Macron got less than 20% in the first round. It means that 80% of the votes were not for him, and of the 20% remaining, a lot did not want him but just thought he was the best chance against the far-right candidate. Right when Macron was re-elected, you could say that more than 80% of the people who voted did not want him. That's a problem IMO.
Not even talking about the US presidents...
49% minority = get fucked
<1% minority = here's your new lords and saviours
The opposite (again IMO) is a system where the people votes for a president every 4 years, and invades the Capitol when they lose. BTW Switzerland does not have a president, but instead a group of 7 representing the biggest parties in the country. So there is consensus even at the highest level.
Who? The talking heads paid to do so?
The US is a republic. You could call it a form of democracy, but you would first call it a republic before a democracy. Representativity is what makes it NOT a democracy.
James Madison, a US founding father, felt that (direct) democracy led to mob rule and did not think that people directly voting on issues was a good idea. You can read his opinion from 1788 in the Federalist Papers, #55: https://guides.loc.gov/federalist-papers/text-51-60#s-lg-box...
"Had every Athenian citizen been a Socrates, every Athenian assembly would still have been a mob." - Alexander Hamilton or James Madison
The world of political science is massive. There is no "best" system because once you read through this entire body of study, you realize it consists of compromises. People have been trying to figure this out for a very long time.
