The Twelth Ammendment

The Electors shall meet in their respective states, and vote by ballot for President and Vice-President, one of whom, at least, shall not be an inhabitant of the same state with themselves; they shall name in their ballots the person voted for as President, and in distinct ballots the person voted for as Vice-President, and they shall make distinct lists of all persons voted for as President, and all persons voted for as Vice-President and of the number of votes for each, which lists they shall sign and certify, and transmit sealed to the seat of the government of the United States, directed to the President of the Senate. The President of the Senate shall, in the presence of the Senate and House of Representatives, open all the certificates and the votes shall then be counted. The person having the greatest Number of votes for President, shall be the President, if such number be a majority of the whole number of Electors appointed; and if no person have such majority, then from the persons having the highest numbers not exceeding three on the list of those voted for as President, the House of Representatives shall choose immediately, by ballot, the President. But in choosing the President, the votes shall be taken by states, the representation from each state having one vote; a quorum for this purpose shall consist of a member or members from two-thirds of the states, and a majority of all the states shall be necessary to a choice. And if the House of Representatives shall not choose a President whenever the right of choice shall devolve upon them, before the fourth day of March next following, then the Vice-President shall act as President, as in the case of the death or other constitutional disability of the President. The person having the greatest number of votes as Vice-President, shall be the Vice-President, if such number be a majority of the whole number of Electors appointed, and if no person have a majority, then from the two highest numbers on the list, the Senate shall choose the Vice-President; a quorum for the purpose shall consist of two-thirds of the whole number of Senators, and a majority of the whole number shall be necessary to a choice. But no person constitutionally ineligible to the office of President shall be eligible to that of Vice-President of the United States.

The Twelfth Amendment provides the procedure by which the President and Vice President are elected. It replaced Article II, Section 1, Clause 3, which provided the original procedure by which the Electoral College functioned. Problems with this procedure were demonstrated in the elections of 1796 and 1800. The Twelfth Amendment was proposed by the Congress on December 9, 1803 and was ratified by the requisite number of state legislatures on June 15, 1804.

 Thomas Jefferson gave us the 12^th amendment and was ratified on June 15ht 1804.

Now each state house has a certain amount of votes based on the number of population

Now you know the 12^th amendment. 

The electoral process before the 12th Amendment
By JAMES R WHITSON
May 2000
As laid out originally in the Constitution, the election process was meant to be a contest of individuals not political parties. With an individual like George Washington, whose popularity cut across all groups, this system worked well enough. But during the two elections that followed, the rise of political factions produced some unexpected outcomes. As a result, the 12th Amendment, which changed the way the vice president is elected, was ratified in 1804. Today when an elector casts his ballot he lists one person as his choice for president and another as his choice for vice president. Then two separate lists are drawn up; one with all the names and votes cast for president, and another with all the names and votes cast for vice president. The person with a majority of votes on the presidential list is named president and the person with a majority of votes on the vice presidential list is named vice president. If no one receives a majority of the votes for president, then the House of Representatives chooses from the top three candidates. If no one receives a majority of the votes for vice president, then the Senate chooses from the top two candidates. Before 1804, however, when an elector cast his ballot he listed his top two choices for president. The choices weren't ranked as "first choice" or "second choice" and no mention of vice president was made on the ballot. One list was then drawn up that included both names from every elector's ballot. The person with the majority of votes from the total numbers of electors (not the majority of the total number of electoral votes) was named president. The person with the next highest number of votes was named vice president. If two people had a majority and the same number of votes, then the House of Representatives would choose between them which would be president; the other would be vice president. If no one received a majority then the House would choose the president from the top five candidates. From the remaining four, the one with the most electoral votes would be vice president. If two or more people were tied for second on the list the Senate would choose among them the vice president.

 Originally the election process was meant to be a contest of individuals not political parties. However, this became a problem because If two people had a majority and the same number of votes, then the House of Representatives would choose between them which would be president; the other would be vice president.
