This rather strikes me as a hard sell, since the constitution authorizes a rather broad mandate for securing the orderly business of the people, in and around the Commerce Clause.
Where is the specific constitutional authority for the Federal Goverment to in any way get involved in the public school education of our children or to tax me to pay for it?
Which Article or Clause? The Commerce Clause? Are you kidding?
Again you are attaching as broad a reading of the Commerce Clause as you have on the Establishment Clause. Using your interpretation of the commerce clause anything that ends up in any way "affecting" commerce can be legitimately regulated.
Perhaps you have a Federalist Paper that suggested that this kind of broad mandate to the Federal Goverment was intended by the founders?
