Abstract
First and foremost, the Constitution gives a clear definition of the three main powers described by Montesquieu in Spirit of Laws. Let's remember that the United States of America is a country where a presidential regime predominates. To put it differently, it's customary to say that there is a strict separation of powers. Above all, the first of these powers is the legislative power. Indeed, the first article of the Constitution declared that the Congress had a monopoly over the legislative power. Of course, the laws voted by Congress shall remain subordinate to the Constitution. Besides, the first article explained that the Congress would be divided into two Chambers.
