We will remember that answer when the overturn of Prop 8 is ruled unconstitutional
That is not even a concern at this point. The ruling they will make is obvious.

If you asked me 3 weeks ago I would have put money on the narrow ruling, but after the activities of the last couple of weeks, I would no longer make that bet.
