Good morning. The US supreme court has gutted a major section of the Voting Rights Act through a landmark decision on Louisiana’s congressional map, in a major upheaval in US civil rights law that threatens to weaken the voting power of minorities. In a 6-3 decision along partisan lines, the court demolished section 2 of the Voting Rights Act, the last remaining powerful provision of the 1965 civil rights law that prevents racial discrimination in voting. Section 2 has long been used to ensure minority voters are treated fairly in redistricting. The supreme court found that Louisiana’s congressional maps violated the equal protection clause. Writing for the majority, the supreme court justice Samuel Alito maintained that section 2, which has been used for decades to challenge maps producing racially discriminatory results, does not require states to draw majority-minority districts. How have lawmakers reacted?…
