When to repeal Prop 8?

It's a more difficult question than it sounds: When to try for gay rights advances. It's understandable that some people think "it's always a good time to try." But as recent losses in Maine and other states have shown, when you lose on an issue repeatedly, it sends ripples to other states, that then start to go bad on your issues as well. Losing can set a very bad precedent that has consequences politically. Having said that, I've found that in the past, at times, I've been too conservative in my prognostication as to whether a specific issue was ripe, or whether we should hold back. I said hold back, others went ahead, and they won. So is next year time to repeal Prop 8? Is it timely to be pushing marriage in the states, rather than civil unions or domestic partners (and wait to push marriage later)?
