It's all about the spin. 47% saying someone with religious objections should be required to perform an SSM is shockingly high IMO.
But yea, AP's poll looks to be behind others anyway if it was only at 48% support SSM prior to the ruling. Gallup shows the support at 58-40 right now.
I'm not sure what you mean by spin here, if you look at how the questions were worded. When lawmakers in various states have tried to say that local officials did not have to issue marriage licenses to same-sex couples if they had a religious objection, it was considered extreme and many Republicans even would not have any part of it.
Gallup poll it is clear pushes leaners a great deal more than GfK does. I've seen some numbers that suggest those who don't have a strong opinion tend to go in the direction of supporting SSM when pushed to come down one way or another.
