The Twenty-third Amendment (Amendment XXIII) to the United States Constitution permits citizens in the District of Columbia to vote for Electors for President and Vice President. The amendment was proposed by Congress on June 17, 1960, and ratified by the states on March 29, 1961. The first Presidential election in which it was in effect was the presidential election of 1964. Prior to the passage of the amendment, residents of Washington, D.C. were forbidden from voting for President or Vice President as the District is not a U.S. state. However, they are still unable to send voting Representatives or Senators to Congress. The amendment restricts the district to the number of Electors of the least populous state, irrespective of its own population. As of 2011, that state is Wyoming, which has three Electors. However, even without this clause, the district's present population would only entitle it to three Electors.
