I'm not a lawyer by any means of the word but I do have some common sense. If more that 75% of the states in the United States have Civil Unions for same sex couples wouldn't the federal government have to be including the law for the whole union. If you are married in one state now, it is like you are married in all states and all over the world. So, if we got Civil Unions in over 75% of the states, wouldn't it have to go to the federal laws for the same perks that marriage brings. I do believe that in the states that do have civil unions they do have the same perks in the state that marriage has. They just don't have the federal laws. Then I could be wrong about this, too.
