A generation of Black Americans across the South fought in courtrooms and in the streets during the Civil Rights Movement to dismantle barriers to voting. Their goal was to achieve political representation in a region scarred by the legacy of slavery and its aftermath. One of the crown jewels of that struggle was the Voting Rights Act of 1965, and this week it was hollowed out by the Supreme Court. The majority opinion described racism as a problem of the past. Others saw the decision as another example of its resurgence. The ruling could make it harder for minorities to get elected.
