Opinion of the Court
a District 1 that had a higher BVAP while achieving the
legislature’s political goals. Nor can they explain why, if
such a map can be created, the Challengers’ experts did not
produce one during the trial.
Fifth, the dissent makes much of the fact that Roberts
had taken racial demographics into account in drawing
maps in the past and was aware of the racial makeup of the
various districts he created in this case. But there is nothing nefarious about his awareness of the State’s racial demographics. Roberts has spent nearly 20 years drawing
maps for various state and local initiatives, and it is therefore entirely unsurprising that he exhibited a wealth of
knowledge about who lives in which part of the State. Cf.
Miller, 515 U. S., at 916 (state redistricting officials “will
. . . almost always be aware of racial demographics” during
the districting process). The dissent seeks to undercut Roberts’s credibility by labeling him “a veteran consumer of racial data.” Post, at 18. We think it is unfair for the dissent
to question his credibility simply because he, like every
other expert who has ever worked on a Voting Rights Act
case, has had to “consum[e] . . . racial data” to comply with
our precedents.
Finally, the dissent thinks that the State must have used
racial data because that data, in its view, is more accurate
than political data in predicting future votes. Refusing to
use the racial data, according to the dissent, would have required the “self-restraint of a monk.” Post, at 21. This jaded
view is inconsistent with our case law’s longstanding instruction that the “good faith of [the] state legislature must
be presumed” in redistricting cases. Miller, 515 U. S., at
915. And in any event, there is little reason to think that it
requires much restraint for a mapmaker with a political
aim to use data that bears directly on what he is trying to
achieve, namely, political data. That is especially so where,
as here, the political data, unlike the racial data that the
dissent prefers, took into account voter turnout. See supra,
