2 longshot possibilities are VA with an I-95 district connecting the most Asian and Hispanic parts of NOVA to majority-black parts of Richmond and NC with a district connecting the Lumbee areas to the Research Triangle, though still I doubt the Native/Hispanic/Asian populations are large enough to make it work in NC.
Nope, because most precincts in NoVA still have a substantial white population.
There's some precincts in East PWC with Hispanics/Blacks and relatively few whites but the Asians are more dispersed.
