Cite as: 570 U. S. ____ (2013) 11 GINSBURG, J., dissenting “As against the reserved powers of the States, Congress may use any rational means to effectuate the constitu­ tional prohibition of racial discrimination in voting.” 383 U. S., at 324. Faced with subsequent reauthorizations of the VRA, the Court has reaffirmed this standard. E.g., City of Rome, 446 U. S., at 178. Today’s Court does not purport to alter settled precedent establishing that the dispositive question is whether Congress has employed “rational means.” For three reasons, legislation reauthorizing an existing statute is especially likely to satisfy the minimal require­ ments of the rational-basis test. First, when reauthorization is at issue, Congress has already assembled a legislative record justifying the initial legislation. Congress is en­ titled to consider that preexisting record as well as the record before it at the time of the vote on reauthorization. This is especially true where, as here, the Court has re­ peatedly affirmed the statute’s constitutionality and Con­ gress has adhered to the very model the Court has upheld. See id., at 174 (“The appellants are asking us to do noth­ ing less than overrule our decision in South Carolina v. Katzenbach . . . , in which we upheld the constitutionality of the Act.”); Lopez v. Monterey County, 525 U. S. 266, 283 (1999) (similar). Second, the very fact that reauthorization is necessary arises because Congress has built a temporal limitation into the Act. It has pledged to review, after a span of years (first 15, then 25) and in light of contemporary evidence, the continued need for the VRA. Cf. Grutter v. Bollinger, 539 U. S. 306, 343 (2003) (anticipating, but not guaranteeing, that, in 25 years, “the use of racial prefer­ ences [in higher education] will no longer be necessary”). Third, a reviewing court should expect the record sup­ porting reauthorization to be less stark than the record originally made. Demand for a record of violations equiva­ lent to the one earlier made would expose Congress to a
