On Aug. 7, 2012, Amendment 2 was passed by a wide margin, with 83% voting for it. Amendment 2 basically adds to the Missouri Constitution rights already built into the U.S. Bill of Rights regarding freedom of religion. The only portion of the bill altering current public school practices is the requirement to post the U.S. Bill of Rights in all schools.
