(The Center Square) — A four-year process to clean up Ohio’s voter rolls by 2029 is underway.

Secretary of State Frank LaRose said the plan is to remove outdated or abandoned voter registration, which federal law requires taking four years to complete.

Over the next four years, people removed from the rolls will be mailed notices from their county boards of election with instructions on how to restore their registration to active status.

“Ohio has one of the most efficient and effective voter list maintenance programs in the country,” LaRose said. “Members of the U.S. House Committee on Administration, which helps to oversee our election laws, have been citing Ohio’s voter registration integrity efforts as a model for the nation, and it’s one that’s been upheld by the U.S. Supreme Court. We’ve created a process that’s very transparent so Ohioans can have absolute confidence in the integrity of our elections.”

While election officials begin the new process, LaRose said they are still finishing up the last effort that must be completed by Sept. 23. That purge led to a list of 352,389 voters eligible to be removed from the rolls.

The two federally required are only part of the secretary of state’s maintenance efforts.

County boards perform monthly registration checks and yearly shares voter information with other states to remove people who may have voted with two states.

Also, people who have not voted in two years receive a notice that requires them to take action on their voting status.

The Statewide Voter Registration Database is updated and posted weekly on the secretary of state’s website. Also, Daily Voter Registration Snapshots allow the public to see which registrations have been added, updated or removed each day.
