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.
Vice President of the United States
The vice president is elected indirectly by the voters of each state and the District of Columbia through the Electoral College, a body of electors formed every four years for the sole purpose of electing the president and vice president to concurrent four-year terms. Each state is entitled to a number of electors equal to the size of its total delegation in both houses of Congress. Additionally, the Twenty-third Amendment provides that the District of Columbia is entitled to the number it would have if it were a state, but in no case more than that of the least populous state. Currently, all states and D.C. select their electors based on a popular election held on Election Day. In all but two states, the party whose presidential-vice presidential ticket receives a plurality of popular votes in the state has its entire slate of elector nominees chosen as the state's electors. Maine and Nebraska deviate from this practice, awarding two electors to the statewide winner and one to the winner in each congressional district.
