Twenty-Third Amendment

Section 1.

"The District constituting the seat of Government of the United States shall appoint in such manner as the Congress may direct:

A number of electors of President and Vice President equal to the whole number of Senators and Representatives in Congress to which the District would be entitled if it were a State, but in no event more than the least populous State; they shall be in addition to those appointed by the States, but they shall be considered, for the purposes of the election of President and Vice President, to be electors appointed by a State; and they shall meet in the District and perform such duties as provided by the twelfth article of amendment."

Section 2.

"The Congress shall have power to enforce this article by appropriate legislation."

Thanks to this amendment, the residents of Washington DC can vote representatives in the Electoral College. Since DC is not an actual state, its population can vote for the president or the Congress or a representative in Congress, but nowadays Washington DC can send a representative can talk on behalf of the population but doesn't have the right to vote.

I like this video because it explains about the twenty-third amendment using illustrations and examples that help you understand it better.

In the image we can see the Capitol in Washington DC with a sign hanging of it that says We Want to Vote.
