It doesn't matter that the marriage gap is a problem for the Republicans, because they will never, ever do what it takes to fix it, even though all it would take is holding women responsible for their sexual behavior (or merely taking a hands-off approach and letting them deal with the consequences themselves). We've already crossed that line, and there's no going back until a) we can't afford to indulge them any longer, or b) an authoritarian (probably Democrat) regime comes to power and finds the expense intolerable. Maybe it will be a combination of the two.
