Cite as: 570 U. S. ____ (2013) 23 Opinion of the Court that the Act was “uncommon” and “not otherwise appropriate,” but was justified by “exceptional” and “unique” conditions. 383 U. S., at 334, 335. Multiple decisions since have reaffirmed the Act’s “extraordinary” nature. See, e.g., Northwest Austin, supra, at 211. Yet the dissent goes so far as to suggest instead that the preclearance requirement and disparate treatment of the States should be upheld into the future “unless there [is] no or almost no evidence of unconstitutional action by States.” Post, at 33. In other ways as well, the dissent analyzes the question presented as if our decision in Northwest Austin never happened.

Northwest Austin also emphasized the “dramatic” progress since 1965, 557 U. S., at 201, but the dissent describes current levels of discrimination as “flagrant,” “widespread,” and “pervasive,” post, at 7, 17 (internal quotation marks omitted). Despite the fact that Northwest Austin requires an Act’s “disparate geographic coverage” to be “sufficiently related” to its targeted problems, 557 U. S., at 203, the dissent maintains that an Act’s limited coverage actually eases Congress’s burdens, and suggests that a fortuitous relationship should suffice. Although Northwest Austin stated definitively that “current burdens” must be justified by “current needs,” ibid., the dissent argues that the coverage formula can be justified by history, and that the required showing can be weaker on reenactment than when the law was first passed. There is no valid reason to insulate the coverage formula from review merely because it was previously enacted 40 years ago. If Congress had started from scratch in 2006, it plainly could not have enacted the present coverage formula. It would have been irrational for Congress to distinguish between States in such a fundamental way based on 40-year-old data, when today’s statistics tell an
