The Voting Rights Act of 1965 opened elective offices to blacks in the US South, but systematic evidence on its immediate effects remains scant. Using a novel data-set on black elected officials between 1964-1980, we assess the causal impact of the VRA on the racial make-up of local governments. Since the VRA mandated federal scrutiny (coverage) over a group of Southern counties, we deploy a differences-in-differences estimation strategy using non-covered counties as a comparison group. Our results show that coverage doubled the extent to which black enfranchisement led to gains in black office-holding, particularly among bodies controlling local public finances.
