Look at the trend of the referendums. 2012 NC passed its amendment by the same as CA did in 2000. So 2012 NC was were 2000 era Ca was on the issue, something no one would have predicted in 2000. The court definitely imposed it before too many states would have accepted it, but the trend wasn’t good.
I seriously doubt there is one state that would now pass a marriage amendment by the same or more than it originally did.

The irony is that while acceptance of gay marriage is increasing among whites to include even white conservatives, opposition remains strongest in minority communities that traditionally vote Democrat. Liberals don't like to talk about this.
Would gay marriage pass today in California? Most likely it would but as the state increasingly becomes majority latino and immigrant, the Left may find some pushback that they won't be able to blame on white Baptist Trump voters.
