Final answer:
Three core principles of the United States Constitution are Popular Sovereignty, emphasizing governemental power from the people; Separation of Powers, distributing governmental roles into three branches; and Checks and Balances, ensuring no single branch has too much power.
Step-by-step explanation:
The United States Constitution is built on several core principles that shape the nation and its system of government. Three of these key principles are Popular Sovereignty, Separation of Powers, and Checks and Balances.
Popular Sovereignty refers to the idea that the ultimate source of governmental power lies with the people. This principle is evident from the very beginning of the Constitution in the Preamble, which starts with "We the People." It establishes that the government is created by and for the consent of the governed, ensuring that political power is held by the citizens.
Separation of Powers divides the government into three distinct branches: legislative, executive, and judicial. This distribution ensures that no single branch holds too much power and that the government reflects the will of the citizens. Each branch has unique tasks and responsibilities that are clearly defined in the Constitution.
Checks and Balances is a system embedded in the Constitution to ensure that the separate branches can limit the power of the others, preventing any single branch from dominating. An example of this is the President's ability to veto legislation from Congress, while Congress can override a veto with a two-thirds majority. Additionally, the Supreme Court has the power to declare laws unconstitutional, serving as a check on both legislative and executive actions.
