The administrative divisions of the United States are divided into three levels: states, counties, and cities. Each state has multiple counties under its jurisdiction, and each county has multiple cities under its jurisdiction. A state is the first-level administrative region in the United States, and a state administrative region has considerable sovereignty.

According to the ruling of the Federal Supreme Court, states enjoy judicial sovereignty provided that they abide by two principles: 1. Their sovereignty cannot override the central federal government and the U.S. Constitution; 2. They have the authority to enact their own state constitutions. It cannot exceed the overall sovereignty of the country.

The reasons why the American people promote the expansion of central power in federalism:

1. The dual character of the American nation.

When the early North American immigrants relied on their own abilities to expand territories in the New World and compete on the basis of equality, they created an American nation that has no concept of hierarchy and has an equal and independent character.

However, due to the harsh natural conditions and the revenge of the indigenous Indians, the early immigrants had to rely on each other and help each other, forming the concept of American national collectivism. This constitutes the dual character of the American nation, which is not only suitable for people to accept the central government's protection of collective interests, but also maintains the tradition of local governments to safeguard individual interests.

2. During the anti-British colonial rule, colonial thinkers and politicians had begun to explore the future direction.

In 1767, the American political thinker Dickinson had proposed the implementation of federalism, and Jefferson, Adams and others also proposed this idea. American politicians at the time believed that the Articles of Confederation should be replaced by a central constitution. Politician Madison believed that the Articles of Confederation made the government incompetent, with overlapping agencies, decentralized power, and extremely low efficiency.

In order to establish the authority of the central government, John Adams, Alexander Hamilton, James Madison and others presided over the formulation of the Federal Constitution. The Federal Constitution was adopted on September 17, 1787. The Federal Constitution expanded the authority of the new central power to truly protect "life, liberty, and property" and legitimized the functions of this powerful government.
