Probably. These were between 50 to 70% turnout. The blacks in the country as a whole voted 4% Romney so these inner city blacks were probably 1%. That means out of the 400 there would be 4 Romney votes. The zero vote totals should not be surprising because of the hundreds of all black inner city precincts where the clan or gang is much higher priority than America.
I agree with you. I am actually surprised there aren’t more of these 0 Romney vote precincts. In the inner cities of crime-ridden locations, there is probably not a single Republican voter. That is not hard to believe. It would actually be more surprising if you found a single R voter there...
