A recent analysis by Local Government Information Services (LGIS), which owns this publication, found almost 50,000 duplicate voter registration records, representing Illinois residents who are registered multiple times.

The data, which was pulled from the the Illinois State Board of Elections voter registration file, shows that there were 49,772 records which showed voters with the same first name, middle name, last name and birth date, and registrations at two different addresses or multiple registrations at the same address, with two unique state-issued voter identification numbers.

The total represents 24,843 unique voters, one person registered four times, 84 people registered three times and 24,758 registered two times.

Voters with multiple registrations can vote multiple times.
