10 ALEXANDER v. SOUTH CAROLINA STATE CONFERENCE OF THE NAACP THOMAS, J., concurring in part The Court’s failure is not surprising because the task is futile. The Constitution does not offer “a theory for defining effective participation in representative government.” Holder, 512 U. S., at 897 (opinion of THOMAS, J.). Choosing among theories of effective representation depends on particular voters’ objectives and preferred political strategies, not principles of constitutional law. Are a minority’s votes “more ‘effective’ when they provide influence over a greater number of seats, or control over a lesser number of seats”? Id., at 899. Are minority voters “ ‘represented’ only when they choose a delegate who will mirror their views in the legislative halls,” or does the “practical influence” of a small group of potential swing voters also amount to effective representation? Id., at 900. Only minority voters themselves can answer these questions. No “theory of the ‘effective’ vote” is “inherent in the concept of representative democracy itself.” Id., at 899. So, when our precedents ask a court to determine if a minority’s vote is diluted, they are “actually ask[ing]” the court “ ‘to choose among competing bases of representation—ultimately, really, among competing theories of political philosophy.’ ” Id., at 897 (quoting Baker, 369 U. S., at 300 (Frankfurter, J., dissenting)). The Constitution expresses no view on such issues, and they are not amenable to judicial resolution. In practice, this Court has endorsed a theory of representation that distributes legislative seats in direct proportion to racial demographics. “[T]he ‘lack of any better alternative’ identified in our case law” and the “intuitive appeal” of “direct proportionality” make a racial proportionality standard irresistible. Allen, 599 U. S., at 72 (opinion of THOMAS, J.) (quoting Holder, 512 U. S., at 937 (opinion of THOMAS, J.)). As a result, there is a “near-perfect correlation between [courts’] proportionality findings and [vote dilution] liability results.” 599 U. S., at 72 (citing E. Katz, M. Aisenbrey, A. Baldwin, E.
