The SE suburbs of the old TN-9 are the black flight suburbs. It's our version of Clayton, GA or Prince William, MD. And as one would expect, they're uber Democratic. If you want to read a 350,000 to 30,000 split as a "crack", that's your excessive hyperbole. Pardon the Dems for creating a logical district instead of packing as many blacks in as possible. If you want to talk about who represents whom, at the moment, Marsha almost certainly has more Shelby blacks than Fincher, but whatever. You're not interested in facts. You're interested in creating a paranoid narrative.
Absolutely correct, it's very clear from just looking at the map that Memphis was not split in half or anything. TN-8 barely went into the city limits in the old map.
