Cite as: 602 U. S. ____ (2024) 29 KAGAN, J., dissenting got nowhere in Cooper applies once again. The relevant district in Cooper was super-thin, so that the lion’s share of precincts within it were close enough to a boundary line to be easily moved. See id., at 326. And so too here. Recall that the only issue under review is whether the State improperly moved Black voters from District 1 to District 6— because that is the only gerrymander the District Court found. Now turn to the map of South Carolina’s old districts in this opinion’s Appendix. District 1 was a narrow strip on the Atlantic coast; District 6 ran along its whole length. Nearly everyone within District 1 lived close to the border line; so nearly everyone could have been sent to District 6, consistent with contiguity and compactness. That is true even of people who lived on the beach. Under the State’s districting guidelines, “[c]ontiguity by water is sufficient,” so the mapmakers could—and in fact did—split the new District 1’s land area by pulling District 6 all the way to the water. J. S. A. 541a; see Appendix, infra, at 35, Figure 2 (Inset to 2022 Congressional Map). The upshot is that precinct location did not meaningfully constrain the State’s choice of which voters to move from District 1 to District 6. And so the Challengers’ experts were not required to pretend that it did. 8 That is why the majority, to support its contiguity theory, must use a “simple example” of zero relevance to this case. —————— 8 None of that is to say, as the majority seems to think I say, that all or nearly all District 1 precincts touch the District 1-District 6 line. See ante, at 24–25, n. 8. Some of the district’s precincts are indeed several precincts away from the border. But that fact in no way revives the majority’s objection to the expert reports. Because of District 1’s thinness, almost all of its 300 precincts could (contra the majority) “[ ]realistic[ally]” have been moved, either alone or with a few others, to District 6. Ante, at 23. (And so what if with a few others?: The State generally moved precincts around in clumps.) In other words, the State’s preference for contiguity and compactness left almost all precincts on the table as candidates for removal. The choice of which of those precincts to move must therefore have been explained by other variables, as the Challengers’ experts concluded.
