Registration of Certain Electors by Mail.

The legislature may enact appropriate legislation authorizing and providing for the following persons to register to vote by mail, if they possess the qualifications of an elector and are not disqualified from voting under the Constitution and laws of Alabama, namely, members of the armed forces of the United States, persons employed outside the United States, and the spouses and children of such persons, provided, however, that such persons shall be entitled to register only in the counties where they were residents prior to entering the status which makes them eligible for such registration.
