Developed by the Pew Charitable Trusts and IBM, ERIC uses several databases to compare voters across state lines. The system compares voter list data with Department of Motor Vehicle records, Social Security Administration records, the Postal Service’s national change of address registry and other databases to match voters across state lines; if the system concludes with a high degree of confidence that a John Doe on one state’s voter roll is the same John Doe in another state, the record is flagged.
Is this a good thing? Probably. The main concern is about how the rolls will be cleaned up. Rep. Cohen sent a letter to Secretary Aichele but so far has not heard back from her. The ACLU is also seeking information on how this will work.
