 In her dissent, Justice Ginsburg emphasized the evidential record that Congress had compiled prior to its 2006 reauthorization of the law. That record led Congress to the conclusion that the old coverage formula was adequate to target those jurisdictions where second-generation barriers were most prevalent. For example, the record contained a study showing that covered areas were much more likely to be successfully sued in Section 2 litigation than other jurisdictions. Accordingly, Ginsburg judged that “Congress had reasonably concluded that the coverage formula continues to identify the jurisdictions of greatest concern” (578). She also construed the “equal sovereignty” principle as applying only to the very limited circumstance in which a new state was being admitted to the union: the new state must not be accorded a lesser, or greater, degree of sovereignty than the existing states.
