A Look Inside Our Country's Mind
The system of government in the United States is bicameral, a republic, and a representative democracy. The American government is many layered and equipped with various checks on power. The three branches of the Federal Government, (Executive, Legislative, and Judicial), function independently yet complement, influence, and balance each other. Most importantly, each individual branch has the means to prevent either of the other branches from becoming too powerful.
Established by the Constitution, the government in the United States is a system of law. The original laws are those set forth by the Constitution of the United States and are called constitutional laws. Laws other than constitutional laws are created and changed within the legislative branch, signed or vetoed within the executive branch by the President, and upheld or not by the judicial branch; in some cases, an executive order by the President or a regulation created by a department within the executive branch create a new law. The latter are referred to as administrative laws. Further, the Constitution itself was written with the possibility of amendment. Each state also has its own constitution, legislative body, and court system. The states and their governments are bound together by Federalism.
Fully understanding all of this involves examining the underlying principles this country was built upon, the framework created in the Constitution, and the three individual branches of government.
