Which of the following countries has the most stable democracy?
The United States has the oldest working written Constitution on Earth. The Constitution is not just a piece of parchment that is consulted only when convenient or expedient, but a living document that has helped produce the most stable government in the world. No constitutional system today has endured so long. And no system has evoked so much admiration and bafflement. Many nations have sought, in varying degrees, to emulate American representative democracy.
