To understand the president better, you must know the qualifications to become the president. You must be a natural born citizen. You must be at least 35 years old. Last, you must have lived in the U.S. for at least 14 years.
The President of the United States is one of the 3 most important parts of our government. The president has several jobs that are unknown to most people. The president has many jobs with each of these titles: Chief of State, Chief Executive, Chief Administrator, Chief Diplomat, Commander in Chief, Chief Legislator, Chief of Party, and Chief Citizen.
As Chief of State, Chief of State, he is the ceremonial head of the government of the U.S. He is then, the symbol of all the people in the nation. "The personal embodiment and representative of their dignity and majesty"-Taft. As Chief Executive, he is the executive power of the United States.
As Chief Administrator, he is heading one of the largest governmental machines the world has known. Today, the President directs an administration with some three million civilian employees. This company spends more than a trillion dollars a year. As Chief Diplomat, he is the chief architect of american foreign policy and the nation's chief spokesman to the rest of the world.
As Commander in Chief, he is the commander of the U.S. armed forces. He controls over 2 million men and women in uniform. As Chief Legislator, he is the architect of it's public policy.
The President seems to have a lot of power, yet, checks and balances he isn't an almighty dictator which is a good thing. He has the power to veto bills which is an important part of separation of powers. The presidents veto is to the legislative branch trying to pass a bill, yet they can circumvent him by asking the judicial branch whether the bill they are trying to pass is constitutional or not. So, I'd say the president is very important but not the most important out of the three.
