Tom Goldstein recently completed a study of Judge Sotomayor's race-related cases and concludes:
In sum, in an eleven-year career on the Second Circuit, Judge Sotomayor has participated in roughly 100 panel decisions involving questions of race and has disagreed with her colleagues in those cases (a fair measure of whether she is an outlier) a total of 4 times. Only one case (Gant) in that entire eleven years actually involved the question whether race discrimination may have occurred. (In another case (Pappas) she dissented to favor a white bigot.) She participated in two other panels rejecting district court rulings agreeing with race-based jury-selection claims. Given that record, it seems absurd to say that Judge Sotomayor allows race to infect her decisionmaking.
