The provision in the Constitution that ensures popular sovereignty is the Preamble, which begins with the phrase "We the People." This phrase emphasizes that the power of the government is derived from and granted by the people, establishing the principle of popular sovereignty.
Although, the constitution is many years old The Constitution is still the basis of government because no one has successfully rebelled against. The constitution was made So that America should have basic guide lines that all citizens had to follow. No country can be run without order. The constitution gives order and rules for the citizens and government to follow. Without the constitution there would be nothing to state how government should be chosen and how it should work, and nothing for the citizens to follow.
