Last summer, the United States Supreme Court invalidated the Section 4 coverage formula in the Voting Rights Act that required jurisdictions with a demonstrated history of voter discrimination to “pre-clear” any changes in voting laws with the Justice Department of a federal court. The ruling effectively neutered Section 5 of the VRA.“Four states formerly covered by Section 5 of the VRA – Texas, Louisiana, South Carolina and Georgia – rank as the worst offenders."

On Tuesday, President Obama expressed “disappointment” in the Supreme Court's 5-4 ruling in Shelby County v. Holder, which all but eviscerated Section 5 of the Voting Rights Act, and called upon Congress “to pass legislation to ensure every American has equal access to the polls.” Other critics of the ruling, however, were not so temperate in their characterization of what could prove to be a game changer for ongoing efforts to counter voter suppression.

Wednesday will mark the 50th anniversary of the assassination of civil rights leader Medgar Evers, and the timing couldn't be more significant: Any day now, the Supreme Court could strike down a pair of landmark remedies owed in part to Evers' activism. Uncertainty hovers over observances that began at Evers' gravesite at Arlington National Cemetery last week, as the civil rights community warily awaits rulings that might fundamentally change, if not outright limit, minorities' access to college and participation in elections.
