 Public opinion about ethnic diversity on the court " varies widely depending on the poll question 's wording " . For example , in two polls taken in 1991 , one resulted in half of respondents agreeing that it was " important that there always be at least one black person " on the Court while the other had only 20 % agreeing with that sentiment , and with 77 % agreeing that " race should never be a factor in choosing Supreme Court justices " . It is claimed that the Presidents who have appointed Justices to the Supreme Court in recent years have taken race and religion into account , causing it to be unrepresentative of the U.S. population in general . At the current time , no white Protestant serves on the Court , despite the fact that white Protestants are the largest single demographic group in the United States .
