Cite as: 602 U. S. ____ (2024) 9 Opinion of the Court the record. 5 Under the Senate’s open-door policy, Roberts drew maps upon request for Republican and Democratic Senators alike. In making these maps, Roberts relied on political data from the 2020 Presidential election along with traditional districting criteria and input from various lawmakers, including Representative Jim Clyburn, whose recommendations would have preserved the strong Democratic tilt in his district (District 6) and included a version of District 1 with a black voting-age population (BVAP) of 15.48%. J. S. A. 127a. The eventual map (Enacted Plan), see Figure 2, infra, at 12, differed from the 2011 map in three important respects that reflected the legislature’s priorities. First, the Enacted Plan unified Beaufort and Berkeley Counties within District 1. This move enhanced the Republican advantage in District 1 because the moved-in portions of those counties leaned Republican. Second, to further increase the Republican lead in District 1, Roberts also put more of Dorchester County in District 1. These changes exacerbated the population imbalance between District 1 and District 6. Third, to cure this problem, Roberts moved a series of precincts in Charleston from District 1 to District 6. In keeping with the legislature’s partisan objectives, the precincts moved out of District 1 had a 58.8% Democratic vote share. By design, the legislature divided Charleston between Districts 1 and 6. This split was seen as in Charleston’s best interests because it meant that the county would have two Representatives in the House—one Democrat, Representative Clyburn, who has represented District 6 since 1993 and has held important House leadership positions, —————— 5 During the proceedings, one of the judges described Roberts as “a very precise guy” and a “good man.” J. S. A. 74a, 421a. That judge also remarked that he “always liked asking [Roberts] questions,” that “the legislature’s blessed to have Mr. Roberts,” and that if Roberts says a report is not accurate, “that’s good enough for [him].” Id., at 74a–75a, 254a, 263a.
