Originalist Sin: the Founding Fathers not only supported mandates, they passed laws imposing them

The five conservative justices on the Supreme Court—Thomas, Alito, Scalia, Roberts and Kennedy—cloak themselves in the myth that they are somehow channeling the wisdom and understanding of the Founding Fathers, the original intent that guided the drafting of the Constitution.  I believe the premise of their argument is itself suspect: It is not clear to me how much weight should be given  to non-textually based intent that is practically impossible to discern more than 200 years later. Most of the issues over which there is constitutional dispute today could not even have been envisioned when the document was drafted.
