Is it fake when it is not in proportion?
Natural born citizens commit far more vote fraud than non-citizens. And legal non-citizens commit far more vote fraud than illegals.
Most vote fraud is committed by citizens using the names of others, both other citizens and non-citizens. So when you see the name of a non-citizen who is registered to vote and voted, it is most likely it was a citizen who committed the fraud.
The fraud in Detroit was done by poll workers, but not in the name of anyone. They just electronically stuffed the ballot box.
I am a naturalized citizen since June 12, 1977, and before getting my citizenship it never entered my mind to vote in any election.
