24 ALEXANDER v. SOUTH CAROLINA STATE CONFERENCE OF THE NAACP KAGAN, J., dissenting aspect of a witness’s testimony, including demeanor, tone of voice, and facial expression. They could see when the witness was at ease and when he stumbled. And after taking account of all those cues, the three judges all reached the same conclusion about Roberts and Campsen. They thought that those two witnesses were not telling the truth. The panel was especially disbelieving of Roberts, if almost in spite of itself. The court (contra the majority) well understood what the presumption of good faith required. The judges were predisposed, as the majority has to acknowledge, to think that this “good man,” who had for so long been a fixture on the South Carolina political scene, would play it straight. Ante, at 8–9, and n. 5 (citing J. S. A. 23a, 74a–75a, 254a, 263a, 421a). But in the end, the court felt compelled to find that Roberts’s old habit of relying on race died hard. To the panel, the mapmaker’s tale did not hang together. He said he did not consider race in drawing lines; but he could recite “off the top of his head” the racial breakdown of particular precincts in District 1. 649 F. Supp. 3d, at 191. Those “highly accurate” estimates, the court noted, reflected Roberts’s obvious knowledge of “the racial demographics of the state down to the individual precinct level.” Ibid., n. 12. And Roberts never did—never could—explain why he put so much racial data on his computer screen if not to look at it as he drew district lines. Especially given the surrounding evidence, the court found, Roberts’s “claim that he did not consider race” in excluding voters from District 1 “rings hollow.” Id., at 191 (internal quotation marks omitted). On normal clear-error review, that credibility judgment would control. And so too for Campsen, who obfuscated at every turn. At trial, Campsen reversed his own deposition testimony about whether state senators knew the racial makeup of their districts. (First they knew, then he couldn’t possibly speak for them.) See J. S. A. 377a–378a. He answered as simple a question as whether “race and party are correlated
