“To me kind of the dark-horse question … the long-shot question on this – gets to the fundamental structure of the country and that is defining the rights and privileges under marriage a state function, and a state jurisdiction?

Fisher believes the Supreme Court will rule in favor of the plaintiffs that include April DeBoer and Jayne Rowse, two Hazel Park nurses, and say that states have to recognize same-sex marriage.
