Editor’s note: This is the final installment of an 11-part series on the Constitution of the United States. This article contains the text as written and explanations of articles and amendments. Spelling and grammar are as the original text was written. Explanations contained in this article are not based on the writer’s opinion; they are based on interpretations mainly from Congress and the Supreme Court. The explanations are contained in brackets [] to distinguish them from the actual text of the Constitution. Italicized text indicates words and passages of the Constitution that were changed or affected by amendments.

Amendment XXIII (1961) – 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.

[The Twenty-third Amendment extends the right to vote in presidential elections to citizens residing in the District of Columbia by granting the District electors in the Electoral College, as if it were a state. When first established as the nation’s capital in 1800, the District of Columbia’s five thousand residents had neither a local government, nor the right to vote in federal elections.]

Amendment XXIV (1964) – Section 1. The right of citizens of the United States to vote in any primary or other election for President or Vice President for electors for President or Vice President, or for Senator or Representative in Congress, shall not be denied or abridged by the United States or any State by reason of failure to pay any poll tax or other tax.

Section 2. The Congress shall have power to enforce this article by appropriate legislation.

[The Twenty-fourth Amendment prohibits a poll tax for voting. Although passage of the Thirteenth, Fourteenth, and Fifteenth Amendments helped remove many of the discriminatory laws left over from slavery, they did not eliminate all forms of discrimination. Along with literacy tests and durational residency requirements, poll taxes were used to keep low-income citizens from participating in elections. The Supreme Court has since struck down these discriminatory measures, opening democratic participation to all.]

Amendment XXV (1967) – Section 1. In case of the removal of the President from office or of his death or resignation, the Vice President shall become President.

Section 2. Whenever there is a vacancy in the office of the Vice President, the President shall nominate a Vice President who shall take office upon confirmation by a majority vote of both Houses of Congress.

Section 3. Whenever the President transmits to the President pro tempore of the Senate and the Speaker of the House of Representatives his written declaration that he is unable to discharge the powers and duties of his office, and until he transmits to them a written declaration to the contrary, such powers and duties shall be discharged by the Vice President as Acting President.

Section 4. Whenever the Vice President and a majority of either the principal officers of the executive departments or of such other body as Congress may by law provide, transmit to the President pro tempore of the Senate and the Speaker of the House of Representatives their written declaration that the President is unable to discharge the powers and duties of his office, the Vice President shall immediately assume the powers and duties of the office as Acting President.

Thereafter, when the President transmits to the President pro tempore of the Senate and the Speaker of the House of Representatives his written declaration that no inability exists, he shall resume the powers and duties of his office unless the Vice President and a majority of either the principal officers of the executive department or of such other body as Congress may by law provide, transmit within four days to the President pro tempore of the Senate and the Speaker of the House of Representatives their written declaration that the President is unable to discharge the powers and duties of his office. Thereupon Congress shall decide the issue, assembling within forty-eight hours for that purpose if not in session. If the Congress, within twenty-one days after receipt of the latter written declaration, or, if Congress is not in session, within twenty-one days after Congress is required to assemble, determines by two-thirds vote of both Houses that the President is unable to discharge the powers and duties of his office, the Vice President shall continue to discharge the same as Acting President; otherwise, the President shall resume the powers and duties of his office.

[The Twenty-fifth Amendment clarifies what happens upon the death, removal, or resignation of the President or Vice President and how the Presidency is temporarily filled if the President becomes disabled and cannot fulfill the responsibilities of the office. It supersedes the ambiguous succession rule established in Article II, Section 1, Clause 6. A concrete plan of succession has been needed on multiple occasions since 1789. However, for nearly 20% of U.S. history, there has been no vice president in office who can assume the presidency.]

Amendment XXVI (1971) – Section 1. The right of citizens of the United States, who are eighteen years of age or older, to vote shall not be denied or abridged by the United States or by any State on account of age.

Section 2. The Congress shall have power to enforce this article by appropriate legislation.

[The Twenty-sixth Amendment prohibits the government from denying the right of United States citizens, eighteen years of age or older, to vote on account of age. The drive to lower the voting age was driven in large part by the broader student activism movement protesting the Vietnam War. It gained strength following the Supreme Court’s decision in Oregon v. Mitchell (1970).]

Amendment XXVII (1992) – No law varying the compensation for the services of the Senators and Representatives shall take effect, until an election of Representatives shall have intervened.

[The Twenty-seventh Amendment prevents members of Congress from granting themselves pay raises during the current session. Rather, any raises that are adopted must take effect during the next session of Congress. Its proponents believed that Federal legislators would be more likely to be cautious about increasing congressional pay if they have no personal stake in the vote. Article I, section 6, Clause 1 has been affected by this amendment, which remained pending for over two centuries as it contained no time limit for ratification.]
