30 ALEXANDER v. SOUTH CAROLINA STATE CONFERENCE OF THE NAACP KAGAN, J., dissenting Ante, at 23. Says the majority: District 6 “precincts near [Colleton C]ounty’s northern border with Bamberg County could not have been moved into District 1 without egregiously flouting the State’s important interests in contiguity or compactness.” Ante, at 24. That is true: As the map shows, District 6 is fat, and the precincts the majority mentions are far away from the District 1-District 6 line. See Appendix, infra, at 35, Figure 1. But of course this case has nothing to do with those outermost District 6 precincts, or even with the closer-in District 6 precincts that could have been moved into District 1. The sole issue here, again, is whether the State disproportionately selected heavily African-American precincts to move out of District 1. When it gets around to that issue, the majority says: “[T]he same problem” as in its example “arises with respect to the question whether a precinct in District 1 . . . could have been moved into District 6.” Ante, at 24. But that is not true, for self-evident reasons. As just described—and shown on the map—the old District 1 was thin, and the great bulk of its precincts were close to the District 1-District 6 line. See Appendix, infra, at 35, Figure 1. So they could have been moved “without egregiously flouting”—actually, without flouting at all—“the State’s important interests in contiguity or compactness.” Ante, at 24. The majority’s inapt comparison is revelatory in one sense only: It shows why appellate courts are supposed to use a clear-error standard—to make sure we are fixing, not introducing, mistakes. The majority’s other main criticism, aimed solely at Ragusa, is original to this Court: It was never raised or considered below (or, as far as I know, in other voting suits). The objection relates to the way Ragusa measured each precinct’s partisan tilt. He asked how many 2020 Biden voters lived in a precinct relative to its voting-age population. So, for example, a 1,250-person precinct with 700 Biden voters would count as much more Democratic than the same-sized precinct with 350 Biden voters. The majority says that
