At least the preamble. No wait, the Preamble and the Bill of Rights.
Our son was studying this in his 'gifted' class and his sheet on the Bill of Rights had for the second amendment "The right to have Weapons". He had crossed that out and put "The Right to Keep and Bear Arms" RKBA baby!! And he knows why that's so important too.
Interesting idea! People may actually get beyond reading the First Amendment. Indeed, by reading the First Amendment itself day after day, people just might begin to ask, "WHERE is that phrase - separation of church and state"? Doing a bit of research, the phrase may be found in the private letters of Thomas Jefferson. It may also be found in Article 51 of the Constitution of the former Soviet Union!
