Which amendment provided D.C. with representation in the electoral college?

The 23rd Amendment is significant because it granted residents of Washington, D.C. the right to vote in presidential elections, thereby providing them with representation in the Electoral College. Prior to this amendment, citizens in D.C. were not given any electoral vote due to the district not being a state, which left them without a voice in choosing the President or Vice President. Ratified in 1961, this amendment allowed D.C. to have as many electoral votes as the least populous state, ensuring that its residents could participate in the democratic process at the federal level. This change was crucial for representation and acknowledging the unique status of the capital as a federal district.

The other amendments listed do not pertain to electoral representation for Washington, D.C. The 22nd Amendment deals with presidential term limits, the 24th prohibits poll taxes in federal elections, and the 25th outlines presidential succession and disability. These do not address the issue of voting rights in the context of D.C.'s representation in presidential elections.
