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.
President of Liberia
Currently, the president is elected by popular vote to a six-year term and is limited to two terms. Under the 1986 Constitution, presidential elections utilize a two-round system, wherein a second round of voting is held between the two candidates with the highest number of votes if no single candidate obtains a majority in the first round. Each term begins and ends at noon on the third working Monday in January of the year immediately following the elections. At the time of their inauguration, each president is required under the Constitution to take a presidential oath promising to preserve and defend the Constitution and faithfully execute the law. The oath is administered by the Chief Justice of Liberia in front of a joint session of the Legislature.
