Divining legislative purpose is a dubious undertaking in the best of circumstances, but the task is all but impossible in gerrymandering cases. “Electoral districting is a most difficult subject for legislatures,” a pure “exercise [of] the political judgment necessary to balance competing interests.” Miller, 515 U. S., at 915. We have therefore cautioned courts to “be sensitive to the complex interplay of forces that enter a legislature’s redistricting calculus.” Id., at 915–916. In cases without smoking-gun evidence, the only practical way to prove that a State considered race when drawing districts is to “show that the State’s chosen map conflicts with traditional redistricting criteria.” 1 Ante, at 3. The Court’s racial gerrymandering precedents use the term “ ‘traditional districting principles’ ” to refer to the “competing interests” and “complex . . . forces” involved in drawing districts. Miller, 515 U. S., at 915–916, 919 (quoting Shaw, 509 U. S., at 647). Judging a map’s consistency or conflict with traditional districting principles requires a court to ascertain what kinds of maps should result from the application of those principles. Determining how a legislature would have drawn district lines in a vacuum is a fool’s errand. Indeed, as we have defined them, “traditional districting principles” are simply anything relevant to drawing districts other than race. They include “principles such as compactness, contiguity, and respect for political subdivisions.” Id., at 647. They also include “keeping communities of interest together, and protecting incumbents,” Rucho, 588 U. S., at 706–707, as well as “minimizing change,” Alabama Legislative Black Caucus v. Alabama, 575 U. S. 254, 259 (2015). Today, the —————— 1 As the Court observes, the most common direct evidence that a State considered race in drawing a districting plan is the State’s admission that it considered race in order to comply with our Voting Rights Act precedents.
