The Executive Branch - Political System USA
The president has come to symbolize the nation's executive branch of government because the Constitution states very clearly that it is the president's duty to "take care that the laws be faithfully executed."
To implement the policies and laws of the nation, the president presides over a vast organization
of departments and agencies which were never enumerated in the Constitution, but developed over the
course of American history.
Although the United States is often cited as an example of a democratic system where the president has a very powerful rule, the formal powers of the office are few and structure of the American government prevents
the president from acting directly, without the advice and consent of the other branches of government.
