The Constitution IS pretty weak though. It's not self interpreting and even following the "Founder's Intentions" can have some pretty horrifying results, like abortion being legal until quickening. Or the fact modern Evangelicals are much better Christians than the "Founders", who, when not paying lip service to Christianity rarely attended Church, rarely prayed, and were often complete moral failures. How does the Constitution enforce itself? Unlike law of tradition, it's words can be twisted by silver tongued "Justices" and politicians.
