FINALLY, AN AG WHO UNDERSTANDS HIS DUTY:   But unfortunately, it’s not Eric Holder.  Arkansas AG Dustin McDaniel, a Democrat, supports same-sex marriage but has vowed to defend in court Arkansas’s state constitutional amendment limiting marriage to one man, one woman.  I will give kudos to this guy, who–unlike too many of his fellow Democrats these days–puts the law ahead of his own personal preferences, unless/until a court declares the law unconstitutional.
