In my opinion, it’s a bit misleading to attribute the transition to district based election to potential attorney letters. As you might have known, FUHSD Board just decided to transition because some people were pushing for it.
The intent of CVRA was that in case there is racialized voting (people voting according to racial lines), district based election might help minorities, assuming that minorities concentrate in one district.
But that’s not the case for a racially diverse area like Silicon Valley. People here don’t congregate by race in where they live.
Splitting FUHSD into 5 districts, in fact, split up Chinese votes since there is not enough Chinese votes in any one district, similarly to ethnic groups.
Chinese voters might not all support Chinese candidates but they might support candidates who share their values on education. Splitting them up into districts, splitting up their voting power.
