Appeals Court Smacks Down Indiana’s Purge Process: An appeals court on Tuesday schooled Indiana on why it is illegal to purge people off the rolls without first giving them a warning. Indiana was using CrossCheck — an interstate database that finds matches of people who appear to be registered in multiple states — to automatically purge voters without first sending them the notices mandated by the National Voter Registration Act. With the appeals court’s decision, a lower court’s freeze on the practice will stay in place while the case is litigated.
