I don't have any real stake in this issue, but would black people be "better off" (however you want to quantify that) with an end to the War on Drugs and a repeal of the Voting Rights Act, or the current status quo?
at this stage it is unlikely that the localized suffrage issues in the South would resurface should the statutory codification of voting rights be removed. furthermore it is likely that even without the VRA courts would interpret the Reconstruction-era amendments as protecting effectively universal black suffrage (as they were of course initially intended, or were at least sold that way). the War on Drugs has significant impact on levels of black educational and employment attainment, as well as of course the disenfranchisement of millions. so I'd have to say this isn't that competitive a question, though interesting.
