The 23rd Amendment to the United States Constitution extends the right to participate in presidential elections to the District of Columbia. The amendment grants to the district electors in the Electoral College, as though it were a state, though the district can never have more electors than the least-populous state. How the electors are appointed is to be determined by Congress. The amendment was proposed by the 86th Congress on June 16, 1960, and was ratified by the legislatures of three-quarters of the states (38) on March 29, 1961. The amendment allows American citizens residing in the District of Columbia to vote for presidential electors, who in turn vote in the Electoral College for President and Vice President. However, the amendment neither grants the District statehood, nor does it provide residents with representation in the Senate or the House of Representatives, though, by congressional legislation, residents have long had the right to elect a non-voting delegate to the House.
