No less than two-thirds shall be selected to represent congressional districts, and each of these candidates shall be a resident of the district which he or she is selected to represent. Congressional district candidates shall be apportioned among congressional districts according to the ratio which the American Independent Party registration in the district bears to the total statewide registration of the party as determined by the
