United States presidential election
United States Constitution
The election of the President and the Vice President of the United States is an indirect vote in which citizens cast ballots for a slate of members of the U.S. Electoral College; these electors in turn directly elect the President and Vice President. Presidential elections occur quadrennially (the count beginning with the year 1792) on Election Day, the Tuesday between November 2 and 8, coinciding with the general elections of various other federal, states and local races. The most recent was the 2012 election, held on November 6. The next election will be the 2016 election, which will be held on November 8, 2016.
Vice President of the United States
Articles of the Constitution
Bill of Rights
The Vice President of the United States is the second highest public office created by the United States Constitution. The Vice President, together with the President of the United States, is indirectly elected by the people through the Electoral College to a four-year term of office. The Vice President is the first person in the presidential line of succession, and would ascend to the Presidency upon the death, resignation, or removal of the President.
An electoral college is a set of electors who are selected to elect a candidate to a particular office. Often these represent different organizations or entities, with each organization or entity represented by a particular number of electors or with votes weighted in a particular way. Many times, though, the electors are simply important people whose wisdom would ideally provide a better choice than a larger body. The system can ignore the wishes of a general membership.
