“The American System is, in many ways, more difficult, certainly far more expensive and much longer than parliamentary system, and I really admire the people who subject themselves to it. Even when I, you know, think they should not be elected president, I think, well you know, good for you I guess, you’re over there promoting democracy and those crazy ideas of yours”
In addition to this quote against a presidential system of government, from Hillary Clinton, Russian President Vladimir Putin puts it even more bluntly: "Look there is parliamentary democracy in most European countries, there is parliamentary democracy in Japan, there is parliamentary democracy in many countries, but in the United States, for some reason… there is a stringent presidential republic."
