Shelby County v. Holder offers three reasons for why the record Congress amassed to support the 2006 reauthorization of the Voting Rights Act (VRA) was legally insufficient to justify the statute's continued regional application: (1) the problems Congress documented in 2006 were not as severe as those that prompted it to craft the regime in 1965; (2) these problems did not lead Congress to alter the statute's pre-existing coverage formula; and (3) these problems did not exclusively involve voter registration and the casting of ballots.
