US Constitution Series, Amendment XXII
Amendment XXII. Presidential TenureThis amendment was proposed and ratified after the death of Franklin D. Roosevelt, who was elected to four terms.
SECTION. 1. No person shall be elected to the office of the President more than twice, and no person who has held the office of President, or acted as President, for more than two years of a term to which some other person was elected President shall be elected to the office of the President more than once. But this Article shall not apply to any person holding the office of President, when this Article was proposed by the Congress, and shall not prevent any person who may be holding the office of President, or acting as President, during the term within which this Article becomes operative from holding the office of President or acting as President during the remainder of such term.
SEC. 2. This article shall be inoperative unless it shall have been ratified as an amendment to the Constitution by the legislatures of three-fourths of the several States within seven years from the date of its submission to the States by the Congress.
Under this amendment, neither Bill Clinton, nor Jimmy Carter nor George Bush may be elected president again. Reading the language, though, a question is raised. If Bill Clinton were elected vice president (which is not expressly prohibited), could Bill Clinton, having been elected president twice, become president again if the president dies in office? I think the answer is no based upon the Twelfth Amendment, but the answer is not entirely clear.
