Cite as: 602 U. S. ____ (2024) 19 KAGAN, J., dissenting at 206a; see id., at 205a. Whatever the particular purpose, he consulted racial data constantly. Now as you know from the majority, Roberts denied doing so in the redistricting at issue here. See ante, at 14–15. But when asked “so in your 20 years of redistricting, this was the only time [that] you didn’t look at race?,” Roberts answered “That’s correct.” J. S. A. 207a. True to his persistent practice (if not to his this-case-only denial), Roberts configured maproom computers to show how every line-drawing decision would affect the new District 1’s racial make-up. In other words, as a mapmaker moved a district line this way or that, he could immediately see the resulting change in the district’s BVAP. Displaying racial data in that way was not an unavoidable feature of the mapmaking software. As one staffer explained: “[Y]ou could configure” the computer setup “in a multitude of ways.” ECF Doc. 462–9, at 114. You could make it so that new BVAP numbers appeared on your screen “while you manipulated geography”—but “there [was] no requirement that you ha[d] to set it up that way.” Ibid. The mapmakers had to choose to display racial data. And here is the key thing: They did. A Senate staffer who often sat with Roberts in the maproom explained that not only “political data” but also “demographic data”—specifically, “race” and “voting age population by race”—was “visible” on computer screens “[a] lot of the time.” ECF Doc. 462–4, at 40. And on cross-examination, Roberts admitted that to be true: Q: So BVAP was visible on the screen while you were drawing maps? A: Yeah. It was in the statistics window at the bottom of the screen. Q: So, you could see BVAP as you were making changes in real time as you were drawing lines? A: We could see the statistics update after a change was made.
