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).
Voting rights in the United States
District of Columbia citizens had voting rights removed in 1801 by Congress, when Maryland delegated that portion of its land to Congress. Congress incrementally removed effective local control or home rule by 1871. It restored some home rule in 1971, but maintained the authority to override any local laws. Washington, D.C., does not have full representation in the U.S. House or Senate. The Twenty-third Amendment, restoring U.S. Presidential Election after a 164-year-gap, is the only known limit to Congressional "exclusive legislature" from Article I-8-17, forcing Congress to enforce for the first time Amendments 14,15,19, 24, and 26. Amendment 23 gave the District of Columbia three electors and hence the right to vote for President, but not full U.S. Congresspersons nor U.S. Senators. In 1978, Congress proposed a constitutional amendment that would have restored to the District a full seat for representation in the Congress as well. This amendment failed to receive ratification by sufficient number of states within the seven years required.
