In a busy week at the Supreme Court, justices narrowly voted to change the very nature of how elections are conducted in Georgia and 14 other states. The court’s 5-4 decision suspended a portion of the Voting Rights Act that requires those states to get prior approval for redrawn districts and other election-related procedures from the Justice Department in Washington. That provision had been in place for nearly 50 years and was the proper remedy in its day to end years of voter discrimination from states that used Jim Crow laws to keep minority voters from the polls.
