The first presidential election in which the District of Columbia participated was the election of 1964. Starting with that election the District of Columbia has consistently had three members of the Electoral College, this being the constitutionally implied minimum number it is entitled to; notwithstanding the constitutionally entrenched limitation on its number of electors, the District's population has never reached the threshold where it otherwise would have been entitled to more than three. Since the passage of the Twenty-third Amendment, all but one of the district's electoral votes have been cast for the Democratic Party's presidential candidates. The Twenty-third Amendment did not grant the district voting rights in Congress, nor did it give the district the right to participate in the process that allows the Constitution to be amended, nor did it grant the district home rule. An unsuccessful proposed constitutional amendment to do this failed in 1978. Many citizens of the district favor statehood or further constitutional amendments to address these issues.
