Any other candidate besides Romney would tear into Obama about this and maybe Romney can find some surrogates who still will. The polls are on our side here and a savvy pol would use it to his advantage.
What is to be gained by tearing into Obama over this? The only people opposed to gay marriage who will vote for Obama are Blacks. And they will vote for Obama even if he promoted
cannibalism. Tearing into Obama wins Romney not one more vote because if a voter is putting gay marriage as his personal third rail for voting, that voter isn’t listening to what’s happening here.
