Public opinion is moving toward acceptance of gay marriage. But it is doing so very slowly, at a rate of perhaps a point or two per year, and has at least a few years to go before it is the majority opinion. In the near term, the more relevant dimension may be 'passion', or depth of feeling. It used to be that the conservatives were ahead on passion -- they were strongly opposed to gay marriage, whereas liberals were, at best, lukewarmly in favor of it. Increasingly, that dynamic seems to be reversing.
