Except that is 59 tests out of 1600. Let's at least assume all 400 people in the division wanted to vote D. Let's say there are 1000 tests of these 400 people (400k out of the 675K blacks). That they got it right 59 out of 1000 times is not impossible. The machines are dumbed down to prevent mistakes.
