There is a lot of noise in the Main Stream Media that there is no evidence that noncitizen voting is a problem with US elections. A frequently cited "study" is a 2016 audit conducted by North Carolina.
However, this audit has major flaw. It only audited people that had DL with non-citizen code who voted. It did not examine was how many illegal aliens with regular DL voted.
The "audit" identified 136 people; 41 (30%) voted illegally, they were not able to contact 61(45%), and they determined that 34 (25%)were actually citizens. The 41 illegal votes are cited as evidence that noncitizen voting is not a major problem.
But major unanswered questions
How many illegal aliens have regular drivers licenses? - FAIR estimates that there are 488,000 illegal aliens in NC. PEW estimates that 72% of illegal aliens are working. If we estimate that 80% of working, illegal aliens have drivers licenses, there would be ~280,000 illegal aliens with regular DL.
How many, if any, are registered to vote? - In 2014 NC found that of the ~10,000 people with a DL with noncitizen code, 1,425 registered to vote. This would equate to 40,000+ illegal aliens registered to vote.
How many, if any, voted? - If the 30-75% seen in the 2016 audit voted, then that would be 12,000-30,000 illegal votes.
Given the importance of election integrity and the relative simplicity of insuring that only citizens vote:
Why haven't these questions been answered?; and
Why is the MSM pretending the questions has been answered?
