ALEXANDER v. SOUTH CAROLINA STATE CONFERENCE
OF THE NAACP
Opinion of the Court
ensures that “race for its own sake, and not other districting
principles, was the legislature’s dominant and controlling
rationale in drawing its district lines.” Miller, 515 U. S., at
913; see also Cromartie I, 526 U. S., at 546 (noting that
strict scrutiny is warranted when a map is “unexplainable
on grounds other than race” (internal quotation marks
omitted)).
Three additional reasons justify this presumption. First,
this presumption reflects the Federal Judiciary’s due respect for the judgment of state legislators, who are similarly
bound by an oath to follow the Constitution. Second, when
a federal court finds that race drove a legislature’s districting decisions, it is declaring that the legislature engaged in
“offensive and demeaning” conduct, Miller, 515 U. S., at
912, that “bears an uncomfortable resemblance to political
apartheid,” Shaw I, 509 U. S., at 647. We should not be
quick to hurl such accusations at the political branches.
Third, we must be wary of plaintiffs who seek to transform
federal courts into “weapons of political warfare” that will
deliver victories that eluded them “in the political arena.”
Cooper, 581 U. S., at 335 (ALITO, J., concurring in judgment
in part and dissenting in part). The presumption of good
faith furthers each of these constitutional interests. It also
explains why we have held that the plaintiff ’s evidentiary
burden in these cases is especially stringent. See Cromartie
II, 532 U. S., at 241.
If a plaintiff can demonstrate that race drove the mapping of district lines, then the burden shifts to the State to
prove that the map can overcome the daunting requirements of strict scrutiny. Under this standard, we begin by
asking whether the State’s decision to sort voters on the basis of race furthers a compelling governmental interest.
Cooper, 581 U. S., at 292. We then determine whether the
State’s use of race is “narrowly tailored”—i.e., “necessary”—
to achieve that interest. This standard is extraordinarily
onerous because the Fourteenth Amendment was designed
