"[US political system] which is regarded as the best example of democracy, globally"
As far as I can tell, Switzerland has the best political system (with the most direct democracy) and it's really a shame that nobody seems to want to imitate it (which of course can be explained by the fact that it means more power goes to the People, not corporations/secret gvt agencies/etc, which are often allowed to buy politicians via "donations", accepted corruption called "lobbying", etc)
