"Draw a district challenge: Whites in 4th place" inspired CA Redistricting Map

[Kamala's side hoe]

It's relatively easy to draw a congressional district where whites are the 4th largest racial group.  I'm curious how far this can go, though.  So, a challenge: Draw a relatively compact congressional district where three minority groups all have at least 28% of the population by CVAP.  Can you hit 29%?  30%???

Alternative: Draw a congressional district where whites are in 4th place, and they trail the racial group that's in 3rd place by at least 18%.  How large can one make this difference?

This may be possible if in the East Bay region if you connect Oakland with San Jose. I'll post any (likely horrendously grotesque looking) updates.

Something along I-880 and I-80 would probably work.

Probably can't be done for the Bay Area; there aren't enough plurality/majority black areas between Richmond and Oakland to get over 19% or so. But if anyone wants to prove me wrong, be my guest.

I managed to get a South Central LAX-Compton-Torrance-Long Beach-Cerritos-Westminster district that's 28.5% Black, 28.4% Asian, and 9.7% Non-Hispanic White. This version completely bypasses downtown LA, and it makes more sense to draw an Inglewood + Long Beach district than an Inglewood + Alhambra one.

It's hard not only because so much of LA County is majority/plurality Mexican, but also because the various Asian-heavy suburbs are far from each other and tend to have a lot of White and/or Latino residents. Long Beach having a lot of super-diverse precincts doesn't help when you're trying to draw a district that's <10% White haha.

I have an Alhambra + Arcadia centered Chinese district (#11), with the (East) Asian-heavy area near the borders with Orange and San Bernardino Counties split among a Downey-Hacienda Heights district (#50), a Covina-Pomona-Chino Hills [SB] district (#48), and the alternate version of Young Kim's district that stretches down to Irvine [Orange] (#12) in my SoCal D gerrymander/“whites in 4th place district with 2020 data” map. I love how DRA has a racial dots feature now with both VAP and general population options.

Did a more "legit" version of my 2021 CA redistricting based on the above PG&D thread, but with no explicit intention to gerrymander outside of Orange County. I tried to align CD boundaries with county and municipal borders as much as possible. I also tried to center some of the Bay Area and SoCal districts around distinct Asian communities of a certain size (e.g. the ethnic Chinese of the San Gabriel Valley, NW Orange County's Little Saigon, the "PMC" and "Blue Collar" Asian cores of Santa Clara County)
