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.
United States presidential line of succession
The United States presidential line of succession is the order in which officials of the United States federal government discharge the powers and duties of the office of President of the United States if the incumbent president becomes incapacitated, dies, resigns, or is removed from office (by impeachment by the House of Representatives and subsequent conviction by the Senate) during his or her four-year term of office. Presidency succession is referred to multiple times in the U.S. Constitution, as well as the 12th Amendment, 20th Amendment, and 25th Amendment. The Article II succession clause authorizes Congress to provide for a line of succession beyond the vice president, which it has done on three occasions. The current Presidential Succession Act was adopted in 1947, and last revised in 2006.
