Why, according to this section of the chapter, does the Creed help us to understand the American way of government and/or politics?

a. American laws, institutions and policies have always lived-up to the ideals expressed in America’s Creed.
b. The full statement of America’s Creed from the Declaration is quoted in the U.S. Constitution and Georgia Constitution.
c. Since the basic principles of the Creed are shared by the mainstream of American politics, the Creed helps us to see what unites the otherwise divided mainstream.
