A president of the United States serves a four-year term. Tenure in the office is the period an individual possesses an elected position. In many countries, there is a statutory restriction on the length of a tenure in office before the elected official must be re-elected. Some governments have term limits, restrict the number of periods an individual can serve in a given position.
The president of the United States of America is the country's head of government. The president is the commanding officer of the United States Armed Forces and supervises the administrative federal agency.
Since its inception, the presidency's power has expanded significantly, as has the government of the united states as a whole. While the presidential authority has ebbed and flowed throughout time, the presidency has assumed greater importance in American democracy since the early twentieth century, with a major growth during Franklin D. Roosevelt's term. As the head of the world's sole surviving global superpower, the president is regarded as being one of America's most famous political personalities in modern times. As the leader of the world's largest economy in respect of nominal GDP, the presidency held great local and worldwide soft and hard power.
Article II of the Constitution creates the executive federal agency and empowers the president with executive authority. The authority comprises the authority to execute and enforce federal law, as well as the authority to designate executive government, legislative, administrative, and judiciary personnel. The current administration is in control of American foreign policy, which is based on constitutional provisions allowing the president the right to choose and accept ambassadors and sign treaties with other countries, as well as later legislation enacted by Congress.
The position entails command of the world's most costly army, which possesses the country's second nuclear deterrent.
The president and vice president are chosen to four components informally through the Electoral College. The Twenty-second Amendment, passed in 1951, states that no individual who has served two consecutive administrations may be nominated to a third. In addition, 9 vice presidents have been elevated to the presidency as a result of a president's death or resignation during his or her tenure. In total, 45 people have held 46 presidencies totaling 58 complete four-year terms.
