“ By holding that, as a federal constitutional requisite, both houses of a state legislature must be apportioned on a population basis, we mean that the Equal Protection Clause requires that a State make an honest and good faith effort to construct districts, in both houses of its legislature, as nearly of equal population as is practicable. We realize that it is a practical impossibility to arrange legislative districts so that each one has an identical number of residents, or citizens, or voters. Mathematical exactness or precision is hardly a workable constitutional requirement. ”

“ But if, even as a result of a clearly rational state policy of according some legislative representation to political subdivisions, population is submerged as the controlling consideration in the apportionment of seats in the particular legislative body, then the right of all of the State's citizens to cast an effective and adequately weighted vote would be unconstitutionally impaired. ”

“ A consideration that appears to be of more substance in justifying some deviations from population-based representation in state legislatures is that of insuring some voice to political subdivisions, as political subdivisions. Several factors make more than insubstantial claims that a State can rationally consider according political subdivisions some independent representation in at least one body of the state legislature, as long as the basic standard of equality of population among districts is maintained. ”
