President of Argentina
Under the 1994 constitutional amendment, the President serves for four years, with a possibility of immediate reelection for one more term. However, unlike the President of the United States, in Argentina, a person may be reelected again after serving for two terms and staying out of office for the following term. So after serving for two consecutive periods, the president is not allowed to run for a third consecutive one, but may return for the two following elections and so on. There is no limit for a person to be a candidate if he or she does not win the elections.
Presidency
In the United States, a presidential election is held every four years. While transitions between presidents are peaceful, they are highly complicated and expensive. After the president-elect is sworn in, one of his primary obligations is to build his administration. The most publicized of these duties is appointing members of his Cabinet (Secretary of State, Secretary of Treasury, Secretary of Defense, et cetera). In total, the president makes 6,000 to 9,000 appointments, although he has the right to appoint as many as 700,000 to the federal bureaucracy. Sometimes, a president will allow appointments from the previous administration to maintain their position. "Normally these appointments include: Cabinet Officers and heads of other executive branch agencies; Under Secretaries; Assistant Secretaries; Directors of Bureaus and Services; and Chairpersons and Members of Boards, Commissions, and Committees. Theses appointments are often authorized by specific provisions of law or approved by the Senate. "
