Gov. Mikie Sherrill (D-NJ) said a software error in New Jersey's motor vehicle commission mistakenly registered thousands of non-citizens to vote.

The incident raises concerns about the integrity of voter rolls and the reliability of automated registration systems used by state governments. While the error allowed ineligible residents to be added to the rolls, officials are now working to determine the impact on actual election results.

The glitch occurred within the state’s motor vehicle commission voter registration system between June 2025 and June 2026 [2]. According to reports, approximately 6,600 [2] non-citizens were registered due to the error, though other reports cite the number at 6,500 [1].

Sherrill addressed the issue on Tuesday, describing the failure as a breakdown in administrative oversight. "Let me be clear: this entire situation is unacceptable," Sherrill said.

Despite the high number of registrations, state officials said the number of ineligible votes cast was significantly lower. Sherrill said that fewer than 400 [3] of those registered actually voted, based on a preliminary analysis [3]. Other reports describe the number of votes as nearly 400 [4].

The governor's office has not yet detailed the specific technical nature of the software failure that bypassed citizenship verification. The state is currently reviewing the registration process to prevent similar errors in future election cycles.

This registration error occurred over a 12-month period, ending in June 2026, but was not reported until this week [2]. The discovery follows a review of the motor vehicle commission's data integration with the state's voter database.

"Let me be clear: this entire situation is unacceptable."

This event highlights the vulnerability of 'Motor Voter' systems, where voter registration is integrated into driver's license applications. While the actual number of illegal votes cast was small relative to the total registration error, the gap between 6,600 registrations and 400 votes suggests that many ineligible individuals did not attempt to use the registration. However, the incident may fuel political debates regarding the security of automated registration and the necessity of more rigorous citizenship verification at the point of entry.
