ILLINOIS — The Illinois State Board of Elections has notified 59 local election authorities that 774 former inmates of the Illinois Department of Corrections may have had their voter registrations erroneously canceled due to a data-matching error involving both agencies.

Matching based on information forwarded to the State Board of Elections incorrectly categorized the individuals as currently incarcerated when in fact they had completed their sentences and been discharged.

According to the Board of Elections, four individuals in Clinton County were identified, nine in Jefferson County, and two in Washington County were identified as having their voter registration wrongly canceled. None were reported for Marion County.

Under Illinois law, voting rights are suspended during an inmate’s period of incarceration but are restored upon release, though the individual must re-register to vote.

This includes those who are released on parole, on mandatory supervised release and on condition of electronic monitoring.
