I'm fascinated by how important standing was in both of these cases. Here's how (I believe) people voted:
Yes/Yes ("Let's Get This Done") Kennedy, Alito, Sotomayor
Yes on W/No on H ("Slow And Steady Wins Teh Gayz") Ginsburg, Breyer, Kagan
No on W/Yes on H ("") Thomas
No/No ("Maybe If We Punt It Will Just Confuse Everyone Into Silence") Roberts, Scalia
To me, the Yes/No group seems most coherent ideologically: liberals who don't want to things to get too ahead of themselves. Roberts, notably, skipped out on Scalia's Article II, where Scalia rants about how teh gayz are taking over the world and how wonderfully perfect DOMA's abettors are, and instead attached a note that was basically like "take a chill pill, brah". And Kennedy, Alito, and Sotomayor? Weeeird. It might be heartening to the librulz that Kennedy wanted to get things done now, considering his surprisingly bleeding-heart Windsor opinion. I mean, this was positively warm-fuzzies inducing:
Thinking of the children of same-sex married people! Sniff!
