6 ALEXANDER v. SOUTH CAROLINA STATE CONFERENCE OF THE NAACP THOMAS, J., concurring in part Court identifies “the legislature’s partisan interests” as a traditional criterion. Ante, at 19. Even considerations such as a district’s “consistently urban character,” “common media sources,” and inclusion of “major transportation lines . . . implicate traditional districting principles.” Bush v. Vera, 517 U. S. 952, 966 (1996) (plurality opinion). We have readily acknowledged that “[t]raditional redistricting principles . . . are numerous and malleable,” and that “some . . . are surprisingly ethereal and admit of degrees.” BethuneHill, 580 U. S., at 190 (alteration and internal quotation marks omitted). To evaluate whether a map aligns with traditional districting principles, a court must “rank the relative importance of those . . . criteria.” Rucho, 588 U. S., at 708. Without such a ranking, it is impossible to say what kinds of maps the principles should yield. But, that analysis ensnarls courts in a political thicket. Traditional districting principles often conflict with one another, and there is no principled way for judges to resolve those conflicts. Consider the question whether the principles of contiguity and compactness can justify a map that retains a relatively small part of the old district’s core. See ante, at 19, 21. Or, consider whether the principle of keeping communities of interest together can justify uniting one community at the cost of splitting another between several districts, or healing partially an existing split at the cost of introducing a new one. See Allen v. Milligan, 599 U. S. 1, 57, 61 (2023) (THOMAS, J., dissenting). These questions do not ask for legal answers, only political compromises. Judicial resolution of racial gerrymandering claims thus requires precisely the kind of “inconsistent, illogical, and ad hoc” decisionmaking that we have said is beyond the judicial power. Vieth, 541 U. S., at 278. Evaluating compliance with traditional districting principles is further complicated by the fact that many decisions are equally consistent with both a good-faith application of
