10 ALEXANDER v. SOUTH CAROLINA STATE CONFERENCE OF THE NAACP KAGAN, J., dissenting racial lines to engineer the results of elections (without the justification of protecting minority voters’ rights). And litigation to remedy that harm is already none too easy. Because of the complex political context, this Court has required challengers of electoral maps to show that race was not just a single but the “predominant” factor in moving voters between districts. Bethune-Hill, 580 U. S., at 187. That is, and is meant to be, a demanding burden. But once plaintiffs have met it to a three-judge district court’s satisfaction, their hardest job should be done. They should not have to face an upside-down form of clear-error review, in which this Court reverses if it decides there is a “possibility” of seeing the evidence the State’s way. Ante, at 16. The principal effect of that novel rule will be to defeat valid votingdiscrimination claims. And the majority is not yet done putting uncommon burdens on gerrymandered plaintiffs. From now on, those plaintiffs will also be subject to an “adverse inference” unless they present a specific form of evidence—an “alternative map” that would “achieve[ the State’s] legitimate political objectives” while “producing significantly greater racial balance.” Ante, at 30–31 (internal quotation marks omitted). And that inference gives every sign of packing a wallop. The majority labels it “dispositive in many, if not most, cases,” except when the plaintiff presents (1) direct evidence of a gerrymander (say, an email admitting to the targeting of Black voters) or (2) “some extraordinarily powerful circumstantial evidence such as the strangely irregular twenty-eight-sided district lines” in Gomillion v. Lightfoot, 364 U. S. 339 (1960). Ante, at 31 (internal quotation marks omitted). Think about that last category, as the majority frames it. The majority must go back 65 years, to the most grotesque racial gerrymander in the U. S. Reports, to find a case based on circumstantial evidence that could have survived its adverse inference. How better to make the point:
