John DePoe has a page dedicated to the argument.
Paul Copan has numerous writings on the Moral Argument. Here is a short treatment by him.
William Lane Craig frequently uses the Moral Argument. Here is his “The Indispensability of Meta-Ethical Foundations for Morality.” Also of interest is Craig’s debate with Kai Nielson: “God, Morality, and Evil.”
This, of course, is a very select list.
