New Jersey admitted a flaw in its DMV system wrongly registered thousands of non-citizens to vote, raising fresh doubts about election systems.

• A motor vehicle software error registered about 6,600 people to vote in the state.
• Some of those people had said they were not citizens and not eligible, but the system signed them up anyway.
• The mistake fuels long-running distrust of voting technology like electronic voter systems and machines.
• The governor is getting ahead of the story publicly, suggesting the issue was about to come out anyway.

Outlook: Expect more scrutiny of how the registrations happened and whether any ineligible votes were cast.
