Twelfth Amendment to the United States Constitution

Under the original procedure for the Electoral College, as provided in Article II, Section 1, Clause 3, each elector could vote for two persons. The two people chosen by the elector could not both inhabit the same state as that elector. This prohibition was designed to keep electors from voting for two ``favorite sons'' of their respective states. The person receiving the greatest number of votes, provided that number equaled a majority of the electors, was elected President.
