El-Sayed, who is locked in a tight contest with four-term House Democrat Haley Stevens, is a doctor and epidemiologist who has served as public health director for Detroit and then (separately) its surrounding county. The gathering in Rouge Park was one of several “Knock Out the Vote” events El-Sayed has held in these final two weeks before the August 4 primary. Judging by the cheers and scattered “amens,” it was a success. But it was also hard not to notice the complexion of the group.
