Our government is a Presidential Republic. That means that our people are ruled by a president.  So after the president approves something he hands it down to the Supreme Court, Senate, and Congress to approve.  After they approve it, they send it to the Department of Justices of the Counties.  There are also the mayors, who keep track of the cities, and the departments-health, education, agriculture, and law enforcement-that help the citizens with their needs.
