Except for the express limitations provided for in Amendments XIV, XV, XIX and XXVI, voter qualifications for House and Senate elections are largely delegated to the States under Article I, Section 2 and Amendment XVII of the United States Constitution, which respectively state that "The House of Representatives shall be composed of Members chosen every second Year by the People of the several States, and the Electors in each State shall have the Qualifications requisite for Electors of the most numerous Branch of the State Legislature." and "The Senate of the United States shall be composed of two Senators from each State, elected by the people thereof, for six years; and each Senator shall have one vote. The electors in each State shall have the qualifications requisite for electors of the most numerous branch of the State legislatures."

Question: when did the age to vote changed to 18? Let's give stream of consciousness first: <hau> Tambaya: Tsarin Mulki na 26 (ya wuce kuma ya amince da shi a 1971) ya kafa shekarun da za a yi zabe don za ~ en tarayya da na jihohi a shekaru 18, amma ba ya hana jihohi daga kafa ƙananan shekarun zabe.
