The ABC News/Ipsos poll reports 52%-32% support for the decision ("Do you approve or disapprove of the recent decision by the U.S. Supreme Court restricting the use of race as a factor in college admissions"):
The majority includes majorities of both white (60%) and Asian (58%) Americans. Latino and Hispanic Americans are split on the ruling (40% approve vs. 40% disapprove), and the majority of Black Americans disapprove ([25% approve vs.] 52% [disapprove]).
Note that the margin of error is necessarily higher for racial subgroups, especially smaller ones, than for the sample as a whole (for that, it's reported as ±3.5%), even though they were slightly oversampled (with the oversamples being statistically accounted for in the overall results). Note also that, despite the race gap, it's clear that no racial group is even close to homogeneous in its views.
