Civil unions are a state issue.
You're not a candidate for federal office. Saying something "should be left to the states" isn't an actual position.
I think each state should vote on whether civil unions for gay and lesbian couples should be legal or not. Either in the legislature or have a referendum though I prefer the latter over the former.
That doesn't answer the question of what your actual position is on the matter.
Well if I was voting on whether or not civil unions should be legalized in Nevada, I would vote no. Does this answer your question?
