This is a report we put together through Americas Majority Foundation. http://amermaj.org/pdf/Voting-Noncitizens.pdf
Incident of voter fraud documented
Voter fraud exists, it is only a matter of how much. Our own data does not support that any of the past three elections were impacted by voter fraud but there is evidence to suggest that specific elections may have been affected. There is evidence to suggest that voter fraud could have tilted North Carolina from McCain to Obama in 2008, our own data suggests that the possibility that 2016 North Carolina race may have been impacted.
Note the word may have been impacted. An updated study from the Americas Majority Foundation 2017 study will be completed within the next two months.
