COLUMBUS, Ohio -- Ohio will restart its controversial voter purge process in the coming weeks, with a few changes to help prevent eligible voters from being removed from the rolls.

No voter registrations will be canceled before this November's mid-term election because federal law bars cancellations within 90 days of an election, and a special election will be held in August for Pat Tiberi's congressional seat.

But county boards of election can begin identifying voters who have not voted in the past two years and mailing them a "confirmation notice," Ohio Secretary of State Jon Husted advised elections officials in a new directive. Notices must be mailed by Aug. 6.

Voters then have four years to return the notice, update their registration address or vote. If they don't, they will be assumed to have moved out of state or died and their registrations will be canceled.

New this time around: If voters renew their Ohio driver's licenses or ID cards with the address they've registered to vote at, that will count as confirming the address.

No voters flagged during the 2018 "supplemental process" will be removed from the rolls until after the November 2022 election, the directive states.

The supplemental process has been used in some form for two decades to clean up Ohio's voter rolls. It was challenged in court after several voters claimed they were improperly removed from the rolls and were wrongly denied a ballot. The U.S. Supreme Court upheld the method last month, siding with state officials who said failing to respond to the mailed notice was evidence a voter had moved and was ineligible to vote.

Husted outlined new steps that will be taken in light of the decision:

Voters checking their registration through MyOhioVote.com will see if they have been mailed a confirmation notice beginning July 16, an idea that came from

If Ohioans renewing their driver's license or state ID card at the Bureau of Motor Vehicles provide the same address as their voter registration, it will serve as address confirmation for voter roll maintenance purposes. Previously, just renewing a license or ID did not automatically update voter registration information.

County boards will mail a second, "last chance" notice 30 to 45 days prior to cancellation of a voter's registration. Previously, voters were mailed just one notice. Boards can be reimbursed for costs associated with mailing the second notice.

"We continue to find innovative new ways to improve the elections process in Ohio that are consistent with our mission to make it easy to vote and hard to cheat," Husted said in a statement. "These latest efforts ensure we continue to meet our responsibility under the law to keep the voter rolls up-to-date while also providing voters with additional opportunities to maintain their registration."

Husted, a Republican elected in 2011, is on the ballot himself this year as the running mate to gubernatorial candidate Mike DeWine.

Boards are advised to mail notices to voters who did not cast ballots in elections starting with the May 2016 primary and ending with the May 2018 primary. Husted Spokesman Sam Rossi said voters who would have been flagged in 2016 or 2017, when the process was on hold by court order, can also expect to receive a notice if they haven't voted or confirmed their registration information since then.

More than 1 million confirmation notices sent through the process have not been returned. Another 835,884 are at risk of being mailed a notice because they have not voted in the past two years. Cleveland.com made this information available last month in a searchable database, and Husted credited the tool for the new feature on MyOhioVote.com.
