SCOTUS will not be invalidating maps on racial grounds outside its narrowed interpretation of the VRA. That means if one slices and dices black neighborhoods in a way not hewing to neutral redistricting principles, that would make up more than half of a CD, and by doing that, a candidate of their choice is not elected, that is illegal, but no more
What if one slices up neighborhoods to pack black voters?
This sort of map would ensure the 1st being 55% black, it's very obviously a gerrymander but would the courts find it objectionable?
