From Fareed Zakaria in Foreign Affairs from 1997,  The Rise of Illiberal Democracy:

(this may require registration to read the whole article which I encourage. )

It is odd that the United States is so often the advocate of elections and plebiscitary democracy abroad. What is distinctive about the American system is not how democratic it is but rather how undemocratic it is, placing as it does multiple constraints on electoral majorities. Of its three branches of government, one — arguably paramount — is headed by nine unelected men and women with life tenure. Its Senate is the most unrepresentative upper house in the world, with the lone exception of the House of Lords, which is powerless. (Every state sends two senators to Washington regardless of its population — California’s 30 million people have as many votes in the Senate as Arizona’s 3.7 million — which means that senators representing about 16 percent of the country can block any proposed law.) Similarly, in legislatures all over the United States, what is striking is not the power of majorities but that of minorities. To further check national power, state and local governments are strong and fiercely battle every federal intrusion onto their turf. Private businesses and other nongovernmental groups, what Tocqueville called intermediate associations, make up another stratum within society.

The American system is based on an avowedly pessimistic conception of human nature, assuming that people cannot be trusted with power. “If men were angels,” Madison famously wrote, “no government would be necessary.” The other model for democratic governance in Western history is based on the French Revolution. The French model places its faith in the goodness of human beings. Once the people are the source of power, it should be unlimited so that they can create a just society. (The French revolution, as Lord Acton observed, is not about the limitation of sovereign power but the abrogation of all intermediate powers that get in its way.) Most non-Western countries have embraced the French model — not least because political elites like the prospect of empowering the state, since that means empowering themselves — and most have descended into bouts of chaos, tyranny, or both. This should have come as no surprise. After all, since its revolution France itself has run through two monarchies, two empires, one proto-fascist dictatorship, and five republics.
