Which amendment deals with the election of the President and Vice President?

The amendment that addresses the election of the President and Vice President is the 12th Amendment. Ratified in 1804, this amendment was introduced to rectify issues that arose in the electoral process as laid out in the original Constitution. Before the 12th Amendment, the candidate with the most electoral votes became President, while the runner-up became Vice President. This system led to complications and conflicts, particularly in the election of 1800.

The 12th Amendment established a clearer procedure for how the President and Vice President are elected. It requires electors to cast separate ballots for President and Vice President, thereby ensuring that the two offices can be filled by candidates from the same political party, which promotes party unity and coherence in governance. This amendment effectively modernized the electoral system, making it more reflective of contemporary political dynamics.

In contrast, the other amendments mentioned do not relate to the election of these two offices. The 10th Amendment concerns the powers reserved to the states and the people, the 15th Amendment addresses voting rights irrespective of race, and the 21st Amendment repealed the prohibition of alcohol. Each of these amendments plays a significant role in the Constitution but does not pertain to how the President and Vice President are elected
