I see even more problems with getting a constitutional amendment “done.” Which is why it wouldn’t really hurt Fred to support an amendment. It makes a crucial point and it’s very, very, very, very, very, very unlikely ever to pass. And if it ever came close, it would thereby give the states exactly the privilege he claims he wants to give them: they could then decide whether to ratify it.
No one’s asking him to put all his eggs in the amendment basket. He could support this and also support overturning R v W and giving the states authority to decide—he could support all three of them.
But that would be an extreme position, now, wouldn’t it. And Fred’s laid back and nuanced. Romney’s looking better all the time.
