The Johnson County Auditor’s Office received 921 voter registration challenges on Tuesday, Aug. 11, 2026. The challenges filed pursuant to Iowa Code § 48A.14 questioned whether the affected voters continued to reside in Johnson County at the addresses listed on their voter registrations.

Johnson County Elections staff contacted all 921 affected voters to notify them of the challenges and explain their rights and options under Iowa law. 

All challenges questioned whether the voter continued to reside in Johnson County at the address listed on their voter registration. Elections staff worked to contact all 921 affected voters to notify them of the challenge and explain their rights and options under Iowa law.

Following the required challenge hearing on Tuesday, Sept. 1, 2026, the following determinations were made:

• Eighteen voters responded to the notice to cancel their registration or had canceled their registration before the notice was sent.
• Nine voters provided sufficient documentation to resolve the challenge or had voted in Johnson County after the date identified in the challenge documentation and, therefore, were not removed.
• 894 challenges remain subject to review following the Nov. 3, 2026 General Election. Those registrations will be reviewed and removed if the voter has no qualifying activity during the election.

Johnson County Auditor and Commissioner of Elections Julie Persons said the large number of challenges should not be interpreted as evidence of widespread voter fraud or other election misconduct in Johnson County.

She added that the county has a highly mobile population, and voters frequently move within the county, to other counties, or out of state. And while Iowa election officials continually work to maintain accurate voter registration records, many voters do not update their registration immediately after moving. In many cases, voters update their registration when they next participate in an election.

“Johnson County Elections will always take voter registration challenges seriously and will follow the law and protect every voter’s rights throughout the process,” Persons said. “Despite this being a very busy time for our election staff, they were able to process 921 individual challenges while continuing to prepare for November’s general election.”

The Auditor’s Office encourages voters who have moved to update their voter registration as soon as possible. Voters can check the address listed on their voter registration by contacting the Johnson County Elections Office at 319-356-6004, Monday through Friday, 8 a.m. to 5 p.m.
