14 ALEXANDER v. SOUTH CAROLINA STATE CONFERENCE OF THE NAACP KAGAN, J., dissenting districting” is–and is thought by voters to be—“incompatible with democratic principles.” Rucho v. Common Cause, 588 U. S. 684, 718 (2019). So it is scarcely surprising that, during legislative debate, the districting plan’s sponsor responded to charges of a partisan gerrymander by asserting “that’s really not the case.” J. S. A. Supp. 286a. 3 Or that during pretrial proceedings key State witnesses continued to deny partisan motives. Luke Rankin, the Republican chair of the Senate Judiciary Committee, testified in discovery that it was not “a goal of [his] to make” District 1 “more reliably republican.” Id., at 425a. Likewise, a Republican member of the House Redistricting Committee testified that he “never considered partisan gain as a goal” of redistricting, and “never” heard “anyone else” admit that goal either. Id., at 409a–410a. And the Senate Redistricting Subcommittee’s counsel swore that there was “no effort” to make District 1 “more Republican leaning.” Id., at 392a. So the Challengers, prior to trial, were not on notice of a partisanship defense. The State, to be sure, changed tack in the end: A strong case made by plaintiffs can powerfully concentrate a defendant’s mind. But by that time, the Challengers’ mapmaker (Dr. Kosuke Imai) had completed his work, and the trial had begun. Even before looking at the trial evidence, the majority thus places the Challengers in a deep hole. Although this Court recently disclaimed any need for an alternative map, the majority today draws an adverse inference from such a map’s absence. And contrary to settled practice, the majority decrees that, even on clear-error review of a ruling for —————— 3 The majority does not help its cause by noting that two Democratic members of the legislature described the districting plan as a partisan gerrymander. See ante, at 21–22. Even as a districting plan’s proponents deny partisan gerrymandering, a plan’s opponents often allege it. (And both for the same reason—because voters don’t like excessive partisan manipulation of district lines.) That Democrats were attacking the plan as a partisan gerrymander hardly shows that Republicans were likely to defend it in that way.
