Can you link your sources? I don't think Obama ever said that SD's had to follow the votes of their individual states. I think the talking point was that, on a national level, the SD's shouldn't overturn the will of the voters.
I agree with you that this nontroversy is meaningless in the larger scheme of things. But here, on this blog, it's not so meaningless when we have people trying to smear Obama with it. I want to personally thank you for speaking out against this in the Linfar diary.
