Is the United States of America a Christian Nation?

Our homie Mydnite Sun sent us this video, at first I was obstruct by the thought, but then as I really thought about it… it seems this country is not as Christian as many of us think we are.  Yuppp… I said it!  I would be interested to know what you guys think.  Is the United States of America a Christian nation?  Were we founded on Christian principles?  If so, are we straying away from them?
