ALEXANDER v. SOUTH CAROLINA STATE CONFERENCE
OF THE NAACP
KAGAN, J., dissenting
Q: So, if you moved a district line, you could see if the
BVAP went up or down, right?
A: You could see on the statistics what the overall district BVAP would be.
J. S. A. 207a; see J. S. A. Supp. 402a (another staffer acknowledging: “Was I aware of, while I was drawing, what
the racial makeup of what I was drawing was? Yes”).
So Roberts’s testimony presented a puzzle. As the majority highlights, Roberts consistently denied relying on racial
data. See, e.g., ante, at 14–15, 17. But racial data, according to both him and others, was easily accessible—in fact,
was usually visible—on his computer while the line-drawing was going on. And he never explained why it was there.
Why configure a computer to tell you, at every stage of the
mapmaking process, how the slightest change in a district
line would affect Black voting-age population if you weren’t
tracking and manipulating Black voting-age population?
Roberts had no answer.
But there was an obvious reason for attending so closely
to racial data, as even the majority acknowledges: One
surefire way of making a South Carolina district more Republican is to make it less Black. See ante, at 15–16. The
difference between a “Republican tilt” and a “Democratic
tilt” in District 1, notes the majority, is the difference between a 17% BVAP and a 21% BVAP. Ibid. That is because
in recent statewide elections, more than 90% of Black South
Carolina voters—and usually more than 95%—have supported the Democratic candidate. See J. S. A. Supp. 82a.
In South Carolina, to remove a Black voter from a congressional district is pretty nearly to remove a future Democratic vote. That is no secret. So it is small wonder that
racial data was conspicuously displayed on Roberts’s computer. And then small wonder that the District Court found
Roberts to have used that data to draw district lines. See
649 F. Supp. 3d, at 191. More doubt would properly have
