"Justice O’Connor was the Court’s leading supporter of the view that government may not endorse a particular religious belief or take any action that could convey such a “message of endorsement to the reasonable observer.” This view placed her sharply at odds with the four other conservatives on the Rehnquist Court. Thus, when O’Connor was replaced with the much more conservative Justice Samuel Alito, most Court watchers expected this prohibition on government endorsements of religion to fall in short order."
