The Joint Center for Political and Economic Studies recently released 50 Years of the Voting Rights Act: The State of Race in Politics.
The report is critical to understanding the impact of the Act and the future of voting rights. The report provides data on minority voter turnout, racially polarized voting, policy outcomes by race, and the number of minority elected officials from the enactment of the Voting Rights Act of 1965 until today.
For an overview of the report, see the Washington Post, BlackPressUSA, The Nation, and Zoltan Hajnal discussing the report on the PBS NewsHour.
Also, see this article "The Voting Rights Act Thirty Years Later" published by the Joint Center in 1995 and written by David Garrow, who authored Protest at Selma and Bearing the Cross, won the Pulitzer Prize, and was a visiting fellow at the Joint Center in 1984.
