Describe the similarities and differences between the constitution, the declaration of independence, and the bill of rights.

what is the primary difference between the declaration of independence and the constitution?

The Declaration has no legal power  in the United States and the Constitution has legal power.
The Declaration is shorter and heartfelt.  The Declaration is an ideological and philosophical document. The Deceleration is more religious and spiritual 
The Constitution outlines the legal stand point what the setup and powers of what the government are. The Constitution is more to the point.
The Declaration was a document written up to declare to England that America wished to become a separate nation.
The Constitution is the document the governs America. It is the document of laws. The Constitution contains the Bill of Rights, which is a list of rights that we as people and American citizens are lucky to have. Without the rights it would probably be really chaotic.
