Governor Mikie Sherrill (D-NJ) said a software error in the state’s motor-vehicle registration system mistakenly registered approximately 6,600 noncitizens to vote [1].

The incident raises concerns regarding the integrity of voter roll maintenance and the vulnerability of automated registration systems to technical failures. Because the error occurred within the New Jersey Motor Vehicle Commission's database, it highlights a critical point of failure where administrative data intersects with election eligibility.

The governor said on Tuesday that a serious software glitch in the registration database mistakenly added noncitizens to the rolls [2]. The system is designed to process voter registration applications simultaneously with driver's license updates, a common practice in many U.S. states to increase participation.

While thousands were incorrectly registered, the impact on actual election results was smaller. Data indicates that nearly 400 of the incorrectly registered noncitizens actually cast ballots [3].

State officials are currently reviewing the software failure to prevent future occurrences. The error was discovered and disclosed in July 2026 [4]. The administration has not yet detailed the specific nature of the glitch or the timeframe during which the incorrect registrations occurred, but the focus remains on scrubbing the rolls of ineligible voters.

This event follows a broader national debate over the security of voter rolls and the implementation of automatic voter registration. The New Jersey case demonstrates how a single technical flaw in a non-election agency can result in thousands of ineligible entries on an official government list [2].

“Approximately 6,600 noncitizens were incorrectly registered to vote because of a software error”

This error underscores the systemic risks associated with automatic voter registration (AVR) systems. While AVR is intended to increase turnout and efficiency, this incident shows that reliance on motor-vehicle data without redundant verification can lead to ineligible registrations. The fact that nearly 400 noncitizens actually voted suggests that registration errors can translate into illegal ballots, providing a focal point for future legislative debates over voter roll audits and citizenship verification processes.
