This Saturday's rally and march at the Lincoln Memorial in Washington, D.C., billed as the "National Action to Realize the Dream March," will commemorate the "Great March" of 1963. But it is also its own call to action at a moment of increased racial tension, renewed challenges to minority voting rights, and an intense economic crisis in African-American communities. One of the most important demands of the march this year is to push Congress to pass an amendment to the Voting Rights Act that will restore protections for voters of color removed by the Supreme Court's devastating decision in Shelby County, Alabama v. Holder. When the NAACP Legal Defense Fund argued the case in the Supreme Court on behalf of black voters from Shelby County, we cited an extensive, 15,000-page record amassed by Congress that documented ongoing, persistent efforts to get between black and Hispanics and the ballot box and dilute their political power. In a stunning act of "hubris," as Justice Ruth Bader Ginsberg wrote in her dissent, the Supreme Court substituted its own view about the current reality of race discrimination in voting for the evidence amassed in the record.
