While it was not always mentioned by name, several major decisions of the Court in the early 21st century very much involved the history and potential future of the “Blaine Amendment.” Blaine is a general label applied to various provisions in 37 different state constitutions limiting or prohibiting the use of state funds to support religious organizations or sectarian activity. The precise wording and application vary from state to state, and 13 states don’t have one at all. Most Blaine Amendments are actually sections or clauses in their respective state constitutions and not “amendments” at all, but the term has proven persistent. Plus, it’s used in the singular (collectively) or plural more or less interchangeably – so that’s kinda fun.
