KAGAN, J., dissenting
measure may be “statistically permissible”—but still is not
good enough. Ante, at 26. In the majority’s view, Ragusa
should have “account[ed] for” potential variance in precinct
turnout by looking to the Biden net vote instead of the
Biden total vote. Ante, at 25–26. Now I’ll admit: I’m not a
statistician. I can see what the majority is saying, but my
inclination would be to seek out other opinions—including
from Ragusa himself—about the net-vote approach, and
whether it would matter. The problem is I can’t do that
here. The theory is the majority’s brainchild, absent from
the District Court’s proceedings. The State never asked Ragusa about it, before or during trial. The State’s own expert
did not bring it up. The State did not raise it in briefing
below. And most important: Nothing in the trial record suggests that adopting the net-vote measure would have made
a real difference. The majority, to show you why it might,
offers what it calls a “simplified” example. Ante, at 25. For
simplified read “fictional”—meaning, not reflective of any
actual precinct’s vote. And for simplified, also read “unrepresentative”? To take just one example: Maybe there are
some, but I doubt there are many, precincts in which 1,100
of 1,250 voting-age people make it to the polls. See ante, at
26. A number of things about precinct composition and
turnout would need to be true for the net-vote/total-vote distinction to make a significant difference to Ragusa’s analysis—and we know none of them. Sure, it’s fun to play armchair statistician. But it’s irresponsible to reverse a trial
court’s decision—on clear-error review—based on such hypothesizing.
A couple of final attacks fare no better. The majority
faults Liu for testing partisan tilt in District 1 with data
from the 2018 gubernatorial primaries, rather than the
2020 presidential election. The majority confidently declares that because an off-year primary has a lower turnout,
the “[d]ata from [it] is less informative.” Ante, at 28. Liu’s
explanation is deemed unworthy of mention. It was that
