In the United States, the president is elected by the use of the Electoral College. Political parties in each State submit to the State's chief election official a list of individuals pledge to their candidate for president and equal in number to the State's electoral vote; therefore, the members of Congress and employees of the federal government are prohibited from serving as an electoral in order to maintain the balance between the legislative and executive branches of the federal government. After everything has been submitted, the major parties nominate their candidates for president and vice president in their national conventions; furthermore, whichever party slate wins the most popular votes in the State becomes that states electors-so whichever presidential ticket gets most popular votes in a State wins all the electors of the state. The Monday after the second Wednesday of December, each state's electors meet in their respective state capitals and cast their electoral votes-one for president and one for vice president. The electors must vote for a least one person from outside their state, in order to prevent electors from voting only for "favorite sons" of their home states.

Now, the candidate for president with the most electoral votes, provided that they receive an absolute majority of the votes is declared president. Provided that no one obtains an absolute majority of the electoral votes to become president, the U. S. House of Representatives selects the president from among the top three contenders with each state casting one vote and an absolute majority of the states being required to elect. If the no one gets the absolute majority for vice president, the same strategy is required. Once the president and vice president are elected, on January 20, they are sworn into office..
