US Constitution

One of the best places to begin your journey of discovery is with the United States Constitution. There are many places on the internet where you can find copies of the Constitution. This one gives the original text but lets you know when it has changed.
After reading the Constitution, next you want to study it's purpose by examining the different pieces of it. I found the following video series very helpful with covering some of the basics:
1: The Non-Consent of the Governed
2: Interpreting the Constitution
3: The Powers of Government
4: Democracy or Republic
5: Federalism vs Nationalism
6: Who is the Ultimate Arbiter?
7: General Welfare
8: Commerce, Arms, and the Meaning of "Regulate"
I found this blog which also might answer some questions about the Constitution.
