I could explain the history of Michigan to you but it would take hours; what I can say quickly however is that when Michigan was a GOP stronghold, the state government went out of its way to remove political power from the six largest urban areas and thus non-white majority district voters. They talk about "Detroit" and the other cities because they want to demonize and disempower the places BLACK AND BROWN PEOPLE live, to build and maintain fascist power over the state. Period. That's why.
