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.
