A simple list with differences and similarities would be fine
Well, John, I am not going to do your assignment for you, but you can easily find what you need.
Ballotpedia.org has a great article by article summary of the Virginia Constitution. You can readily find article by article summaries of the US Constitution through a simple Google search like this one: http://newshour-tc.pbs.org/newshour/extra/wp.../2/.../summary-of-the-US-Constitution.pdf
That will leave you with a list of what is in both Constitutions, and you simply have to compare them.
