The formula in that section can no longer be used as a basis for subjecting jurisdictions to per-clearance.” Congress, the court ruled, “may draft another formula based on current conditions.” But given the fact that Republicans currently control the House of Representatives and the Senate, many voting rights advocates consider it unlikely that Congress will act to create a new formula.
