Opinion polling is usually flawed on this issue, for a number of reasons. But we have actual votes we can look at.
Prop. 22, CA’s first marriage amendment, passed by 61% in 2000, the same % NC passed theirs by last year, so it is reasonable to think NC is 12 years or so behind CA on the issue. CA’s Prop. 8 passed by 52% in 2008, swinging 9% in 8 years. The thing with this is if our masters in black robes deign to uphold it, they will simply try another popular vote to repeal it. All they need is 50% + 1 vote, seems like some sort of repeal on prop.8 5 years after it originally passed would probably pass now.
That’s the danger, to the state in the modern era, marriage is simply whatever judges, pols, or 51% of voting public think it should be at any one time. And that’s it.

It would be better for the voters to repeal Prop 8 than for the SCOTUS to overturn.
But, as it is now, the dominos are falling and it is just a matter of time when all states have gay marriage.
