What is the most democratic part of the constitution?

Answer 1

The most democratic phrase in the Constitution might be the first three words. "We the People..." suggests that all authority for government lies in representing the will of all the people (citizens) of the United States.

You might also look at the 14th Amendment which has an equal protection clause that is the basis for how individuals have rights that cannot be taken away without due process. Having individual liberties guaranteed makes the US a liberal democracy.

A third place within the three part structure of federal government which the Constitution sets up where you find democracy is the House of Representatives portion of Congress. The intent of the founders to have this body elected every two years and to be in charge of tax and spend policy intended to make it the most democratic portion of federal government. (But the re-election of incumbents into the House is very high and the growing power of lobbies suggests that the House is not truly living up to the democratic design of the late 1700s.
