What is the main role of the President of the United States?

The main role of the President of the United States is to enforce laws. This function is established in the Constitution, which outlines the executive branch's responsibility to ensure that federal laws are carried out effectively. The President serves as the head of this branch and is tasked with administering the law and overseeing the federal administration.

In addition to enforcing laws, the President also has the authority to issue executive orders, appoint heads of federal agencies, and guide the country's policy direction, all of which are vital to the implementation of laws.

While creating laws falls under the legislative branch, primarily Congress, and interpreting laws is the responsibility of the judicial branch, the President's central duty revolves around enforcement. Regulating the economy can be part of the President’s agenda, particularly through various policies and initiatives, but it is not the main role defined in the Constitution. Thus, enforcing laws encompasses the President's most fundamental and significant responsibility in the government structure.
