The document outlines several key American constitutional principles: 1) Popular sovereignty holds that ultimate power comes from the consent of the people. 2) Limited government means the government has limited, enumerated powers and individual rights are protected from government overreach. 3) Separation of powers divides the government into legislative, executive, and judicial branches to prevent consolidation of power. 4) Checks and balances allows each branch to limit the powers of the others through mechanisms like vetoes and appointments. 5) Judicial review established the power of courts to review the constitutionality of laws.
