Cite as: 602 U. S. ____ (2024) 3 Syllabus repeated instructions that a court in a case such as this must rule out the possibility that politics drove the districting process. None of the facts on which the District Court relied to infer a racial motive is sufficient to support an inference that can overcome the presumption of legislative good faith. First, the District Court concluded that the legislature deliberately sought to maintain a particular BVAP because the maps that produced the sought-after partisan goal all had roughly the same BVAP. But the mere fact that District 1’s BVAP remained around 17%, despite all the changes made during the redistricting process, proves very little. The tight correlation between the legislature’s partisan aim and District 1’s BVAP is substantiated by the District Court’s own findings. The Challengers could not point to a single map in the record that would satisfy the legislature’s political aim with a BVAP above 17%. The District Court disregarded the presumption of legislative good faith by drawing an inference that the State acted in bad faith based on the racial consequences of a political gerrymander in a jurisdiction in which race and partisan preference are very closely related. Second, the District Court inferred a racial motive from the fact that the Enacted Plan moved more voters out of District 1 than were needed to comply with the one person, one vote rule, and that the Enacted Plan split a few counties. But the high priority that the legislature gave to its partisan aim can explain these decisions. Third, the District Court clearly erred when it concluded that the legislature’s real aim was racial based on the movement of certain predominantly black Charleston precincts from District 1 to District 6. Again, the legislature’s partisan goal can easily explain this decision. Fourth, the District Court placed excessive weight on the fact that several legislative staffers admitted to viewing racial data at some point during the redistricting process. The District Court cited no evidence that could not also support the inference that politics drove the mapmaking process and provided no explanation why a mapmaker who wanted to produce a version of District 1 that would be safely Republican would use data about voters’ race rather than their political preferences. Pp. 14– 19. (d) The four expert reports relied upon by the Challengers are flawed because they ignored traditional districting criteria such as geographical constraints and the legislature’s partisan interests. Allen v. Milligan, 599 U. S. 1, 34. The report of Dr. Kosuke Imai made no effort to disentangle race from politics. It also failed to consider “core district retention,” a term referring to “the proportion of districts that remain when a State transitions from one districting plan to another.” Id., at 21. The report of Dr. Jordan Ragusa did attempt to disentangle race from politics, but its analysis has two serious defects. First, each
