Is there anywhere besides Mississippi where this might be a possibility? Louisiana maybe? California someday?
What about Hawaii? The lowest white population of any state (about 1/4).
But are whites even a compact minority in any part of Hawaii, or are they fully integrated with Asians and Native Hawaiians/Pacific Islanders? Are their candidates of choice that much different? If they're fully integrated or they share the same candidates of choice, it wouldn't be necessary to make a VRA district (if the VRA applied to whites).
