There is no way to tell the number of illegals that voted. It may be possible to tell the dead voters.Also there are thousands of votes never counted in every election and that is a fact. I do not know if they even know the number or care about it. Between the votes Hillary gets in NYC and California would alone count about 4 million I believe.
The Lord knows exactly the number of illegal votes cast, just as He knows exactly the number of hairs on our heads...
