Cite as: 602 U. S. ____ (2024) 33 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.

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,
