Georgia is planning to eliminate approximately half a million voters from its registration rolls in one of the largest registration removals in U.S. history.

Around 455,000 inactive voter registrations will be removed from the state’s registration list this summer, according to the Atlanta Journal-Constitution. More than half of the registrations that are set to be canceled were identified by the Electronic Registration Information Center, which involves 24 states that identify when a voter moves out of state and is no longer eligible to vote, in this case, in Georgia.
