Interesting on the marriage/partisan issue - my take is less "Are we really so partisan that we’ll now see marriage as a Republican thing, and so if you are a Democrat, you won’t get married?" than it might just be selection bias - if you're unmarried, you may be more likely to be a democrat. I'm not sure whether that's true, but it would seem reasonable given the demographics. So in an extreme example, married people are equally likely to be democrats or republicans, but single people are more likely to be democrats, then republicans are more likely to be married. (Bayes' theorem for the win!?!)
