Twenty-second Amendment to the United States Constitution
The amendment prohibits any individual who has been elected president twice from being elected again. Under the amendment, an individual who fills an unexpired presidential term lasting greater than two years is also prohibited from winning election as president more than once. Scholars debate whether the amendment prohibits affected individuals from succeeding to the presidency under any circumstances or whether it only applies to presidential elections.
2016 United States presidential election
Article Two of the United States Constitution provides that the President and Vice President of the United States must be natural-born citizens of the United States, at least 35 years old, and residents of the United States for a period of at least 14 years. Candidates for the presidency typically seek the nomination of one of the political parties, in which case each party devises a method (such as a primary election) to choose the candidate the party deems best suited to run for the position. Traditionally, the primary elections are indirect elections where voters cast ballots for a slate of party delegates pledged to a particular candidate. The party's delegates then officially nominate a candidate to run on the party's behalf. The general election in November is also an indirect election, where voters cast ballots for a slate of members of the Electoral College; these electors in turn directly elect the President and Vice President.
