The Trump administration has, for the first time ever, built a searchable national citizenship data system.The tool, which is being rolled out in phases, is designed to be used by state and local election officials to give them an easier way to ensure only citizens are voting. But it was developed rapidly without a public process, and some of those officials are already worrying about what else it could be used for.
Whatever the merits of such an idea (none, but let's pretend), a system implemented with no concern for accuracy and no way to correct errors is there for reasons other than the stated ones.
