COOPER v. HARRIS
Opinion of the Court
hearings, drafts, and revisions later, both chambers of the
State’s General Assembly adopted the scheme the three
men proposed.
The new map (among other things) significantly altered
both District 1 and District 12. The 2010 census had
revealed District 1 to be substantially underpopulated: To
comply with the Constitution’s one-person-one-vote principle, the State needed to place almost 100,000 new people
within the district’s boundaries. See App. 2690; Evenwel
v. Abbott, 578 U. S. ___, ___ (2016) (slip op., at 3) (explaining that “[s]tates must draw congressional districts with
populations as close to perfect equality as possible”).
Rucho, Lewis, and Hofeller chose to take most of those
people from heavily black areas of Durham, requiring a
finger-like extension of the district’s western line. See
Appendix, infra. With that addition, District 1’s BVAP
rose from 48.6% to 52.7%. See App. 312–313. District 12,
for its part, had no need for significant total-population
changes: It was overpopulated by fewer than 3,000 people
out of over 730,000. See id., at 1150. Still, Rucho, Lewis,
and Hofeller decided to reconfigure the district, further
narrowing its already snakelike body while adding areas
at either end—most relevantly here, in Guilford County.
See Appendix, infra; App. 1164. Those changes appreciably shifted the racial composition of District 12: As the
district gained some 35,000 African-Americans of voting
age and lost some 50,000 whites of that age, its BVAP
increased from 43.8% to 50.7%. See 2 Record 349 (Fourth
Affidavit of Dan Frey, Exh. 5); id., at 416 (Exh. 11).
Registered voters in the two districts (David Harris and
Christine Bowser, here called “the plaintiffs”) brought this
suit against North Carolina officials (collectively, “the
State” or “North Carolina”), complaining of impermissible
racial gerrymanders. After a bench trial, a three-judge
District Court held both districts unconstitutional. All the
judges agreed that racial considerations predominated in
