Josh Patashnik suggests that Obama could get out of the logical problem he’s in by opposing same-sex marriage prospectively while also opposing the retroactive denial of marriage to same-sex couples who already have it. If that’s his view, though, you’d think he would support the initiative while also opposing its retroactive application. Anyway, if it’s unjustly discriminatory to take away the marriage licenses of same-sex couples who already have it, then it is unjustly discriminatory not to give it to them in the first place.
