Read the article and the ruling seemed to hang on precedent established by the “Gingles Test.” Did Thomas write the majority opinion? I’d like to hear is reasons if he didn’t.
Under the Gingles test, plaintiffs must show the existence of three preconditions:
The racial or language minority group “is sufficiently numerous and compact to form a majority in a single-member district”;
The minority group is “politically cohesive” (meaning its members tend to vote similarly); and
The “majority votes sufficiently as a bloc to enable it ... usually to defeat the minority’s preferred candidate.”[19]:50–51
