Thinking about Prop 8

I regularly read Prop 8 Trial Tracker, a blog that follows the updates in the seemingly interminable trial over California's 2008 initiative proposition 8, which amended the state's constitution to declare that only a marriage between a man and a woman would be legal or valid in the state.  Currently, the anti-Prop 8 (i.e., the pro-LGBTQ) side is winning; they scored a decisive victory in the trial court level, which I was quite excited and energized to see.  Now, on appeal, the opponents of Prop 8 face a tough choice -- would it be preferable to take their big win and walk away, which would be great for California but unhelpful (at least in the short term) to the rest of the country, or is it worth risking that big win by pressing onward to the Supreme Court, where another victory would have national ramifications, but where a loss could set the equality push back years?  The New Yorker ran a piece on these questions awhile back, but it is still just as pressing today, as the wheels of the courts grind slowly on.  What do you think?
