Let me see it is really society changes or a small group of citizens wishing to force their view points on the majority. In every state where this has come up to a vote to the public, gay marriage has been voted down. Only in those areas like MASS, where one judge over ruled the will of the people, do you have it legal.
I don't know what any political has to worry about in Mass as far as over turning a very liberal judges opinion, since it has been proven that the majority of the public do not want it.
