Jeffrey Toobin points out that personal identity has always been a factor in selecting Supreme Court justices:
In the early days of the republic, when
regional disputes were the foremost conflict of the era, nominees were
generally defined by their home turfs. So Presidents came to honor an
informal tradition of preserving a New England seat, a Virginia seat, a
Pennsylvania seat, and a New York seat on the Court. In the nineteenth
century, as a torrent of European immigrants transformed American
society, religious differences took on a new significance, and
Presidents used Supreme Court appointments to recognize the new
arrivals' growing power. In 1836, Andrew Jackson made Roger B. Taney
the first occupant of what became known as the Catholic seat on the
Court.... In 1916, Woodrow Wilson nominated Louis D. Brandeis, establishing the Jewish seat, which later went, with brief overlapping periods, to Benjamin N. Cardozo, Felix Frankfurter, and Abe Fortas.
