Twenty-second Amendment to the United States Constitution
Some argue that the 22nd Amendment and 12th Amendment bar any two-term president from later serving as vice president as well as from succeeding to the presidency from any point in the presidential line of succession. Others contend that the original intent of the 12th Amendment concerns qualification for "service" (age, residence, and citizenship), while the 22nd Amendment, concerns qualifications for "election", and thus (strictly applying the text) a former two-term president is still eligible to "serve" as vice president (neither amendment restricts the number of times an individual can be elected to the vice presidency), and then succeed to the presidency to serve out the balance of the term (though prohibited from running for election to an additional term).
Term limits in the United States
When the states ratified the Constitution (1787–88), several leading statesmen regarded the lack of mandatory limits to tenure as a dangerous defect, especially, they thought, as regards the presidency and the Senate. Richard Henry Lee viewed the absence of legal limits to tenure, together with certain other features of the Constitution, as "most highly and dangerously oligarchic". Both Jefferson and George Mason advised limits on reelection to the Senate and to the Presidency, because said Mason, "nothing is so essential to the preservation of a Republican government as a periodic rotation". The historian Mercy Otis Warren, warned that "there is no provision for a rotation, nor anything to prevent the perpetuity of office in the same hands for life; which by a little well-timed bribery, will probably be done".
