No one is quite sure how many illegal aliens are registered in total, but the number is likely much higher. In a completely separate datapoint, the New Jersey Globe reported that 75,000 illegal aliens were summoned for jury duty. {citation}The 75,000 illegal aliens summoned were from a total of around 1 million sent jury duty notifications. There are currently 6.6 million registered voters in New Jersey. If the calculation is applied that means up to 495,000 registered voters are noncitizens or illegal aliens.
