what was the importance of the twelfth amendment which was ratified in 1804
Twelfth Amendment to the United States Constitution The Twelfth Amendment (Amendment XII) to the United States Constitution provides the procedure for electing the President and Vice President. It replaced the procedure provided in Article II, Section 1, Clause 3, by which the Electoral College originally functioned. Problems with the original procedure arose in the elections of 1796 and 1800. The Twelfth Amendment refined the process whereby a President and a Vice President are elected by the Electoral College. The amendment was proposed by the Congress on December 9, 1803, and was ratified by the requisite three-fourths of state legislatures on June 15, 1804.
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.[2] The person receiving the greatest number of votes, provided that number equaled a majority of the electors, was elected President.
