The latest survey on gay marriage finds 62% of voters in favour and about a third against. This is pretty much unchanged from last year. The issue has gone up the political agenda, thanks largely to the Greens (how I hate to say anything nice about them…), but so far opinion is not moving much.
But the demographics of this issue remain very striking, and look to be a case of demography as destiny in public opinion. The case against gay marriage seems lost. Eventually politics will catch up with opinion, so I think it now a case of when we get gay marriage rather than if.
