If turnout was 160% in some places, then overall turnout of honest voters must have been even lower than 51%, and I'm not assuming anywhere that there was no voter fraud.
Anybody who would vote for race would tend to be a democrat / liberal anyways. You have the racists, most of them democrats. After all, they were the ones that created the KKK.
Then you have the liberals who vote via emotion. They also tend to believe white is supreme and non-whites need that extra help. They are racists too.
Anybody who would vote against the white guy and for the black guy solely out of race is likely to be a democrat and vote for democrats everytime. They tend to be school teachers, union workers, globalist-liberals who think it's time that America learn a lesson from all of its evil ways. They are bleeding-heart liberals anyways.
