The Voting Rights Act of 1965 increased turnout among Black voters, which then generated economic benefits for Black communities. In Shelby County v. Holder (2013), the Supreme Court invalidated the enforcement mechanism responsible for these improvements, prompting concerns that states with histories of discriminatory election practices would respond by suppressing Black turnout. I estimate the effect of the Shelby decision on the racial composition of the electorate using triple-difference comparisons of validated turnout data from the Cooperative Congressional Election Study. The data suggest that the Shelby decision did not widen the Black-white turnout gap in states subject to the ruling.
