The amendment was proposed by the 86th Congress on June 16, 1960 . Ratification by the requisite 38 of the 50 states was completed on March 29, 1961 . </P> <P> The Electoral College, established in Article II, Section 1, Clause 2 of the United States Constitution, is the institution that elects the President and Vice President of the United States every four years . The President and Vice President are not elected directly by the voters . Instead, they are elected by "electors" who are chosen by popular vote on a state - by - state basis . As the District of Columbia is not a state, it was not entitled to any electors prior to the adoption of the Twenty - third Amendment . Citizens living in the district were, therefore, shut out from the presidential--vice presidential election process . The first presidential election in which the District of Columbia participated was the election of 1964 . This amendment mentions the Twelfth Amendment to the United States Constitution when it mentions how the district's electors should perform duties provided by said amendment . </P>
