“I predict the ruling will be 6-3 invalidating DOMA using the equal protection clause. Kennedy will write the majority opinion.”
I would go with that prediction.
However, the big case will be Prop. 8 and the will 6-4 Against Prop. 8 and I’m afraid Roberts will write the majority opinion.
And if Prop. 8 goes down, every state ban will go down with it.
