I would also suggest a reading of the Federalist Papers.
They may be read at the following http://www.foundingfathers.info/federalistpapers/
They explain in detail what the Founding Fathers were trying to accomplish and what the background was for the different amendments.
US Constitution??? I thought congress passed a law making it null and void in 1913. I know here in California it was outlawed and banned from the public in the early seventies. Why do people keep bringing up this 240 year old paper of suggestions for a more perfect union? it really is irrelevant at this stage.
