Cite as: 602 U. S. ____ (2024) 17 KAGAN, J., dissenting the issue was whether the State had advanced its partisan objective primarily by racial means. The Challengers maintained that it had. They said the State’s mapmakers had consciously removed Black citizens from District 1 on the (justified) assumption that doing so would turn the district redder. The State, by contrast, denied in any way using race to draw District 1’s lines. According to its account, the disproportionate removal of African Americans from District 1 was just an accidental byproduct of political sorting—more specifically, of ejecting precincts that had strongly supported then-candidate Biden in the 2020 election. 4 Faced with those competing stories, the District Court had to decide which to credit. The court’s decision to credit the Challengers, as I’ll next show, was not clear error—indeed, far from it. There was of course evidence pointing in each direction; like Cooper, this was a “two-sided case.” 581 U. S., at 307, n. 6. But the Challengers made a weighty showing that the mapmakers relied substantially on racial data in moving voters around. The mapmakers had the incentive to do so, given the limits of the political information in their possession. They had the ability to do so—both access to data and experience using it. And direct testimony showed that the mapmakers had in fact continually examined racial data during the line-drawing process. The map yielded by that process hit on the dot the Black voting percentage that state officials —————— 4 A notable feature of this case is that the State chose to litigate it in categorical terms, claiming that the new district lines were based only on political data and not at all on racial data. The State did not need to go that far. In a gerrymandering case, a defendant can prevail by arguing that although race played some role in redistricting, it was not the “predominant factor.” Miller, 515 U. S., at 916. The State’s eschewal of that more moderate assertion turned the factual issue about what its mapmakers did into a binary choice. I therefore mainly address it in those terms, though the Challengers’ evidence was powerful enough to support a finding of gerrymandering even had the State put predominance at issue.
