Yes, there is plenty of speculation, and I may not be qualified to speculate. Then again, we have the brightest legal minds in the country at AFER certain that our side will win both cases, and we have NOM and their side absolutely certain that their side will win both cases. So it seems like my unqualified opinion might be just as good as anyone's.<quoted text>
Nope, you're not wrong about the voting to repeal Prop 8 IF and that's a big IF SCOTUS should rule it Constitutional, BUT I believe that SCOTUS is specifically looking at the Prop 8 case with regards to the Article 3 Standing issue and if they rule that the proponents of Prop 8 did not have standing, then they will more than likely overturn the 9th's ruling and uphold Judge Walker's ruling, but I'm pretty certain that there will be PLENTY of speculation on how SCOTUS will rule between now and June of 2013.
What I worry is that these two cases were taken as a means to expand state's rights. From that view, SCOTUS might very well rule that CA citizens have the right to define their constitution withot interference from the federal government. They might simultaneously rule that the right of states to define marriage binds the federal government--or not.
Personally, I don't think the majority of SCOTUS will be impressed by the Romer precedent. Romer was overturned because it was too broad, taking away the right of a minority to even request rights and protections from the state. Whereas Prop 8 took away specifically the right to marriage but left GLBT's free to (successfully) pursue substantially all the rights and benefits thereof, the parallel is weak.
