The transition team is probably looking at this and decided to float Romney's name.
Looking at different comments on this, SOS is so important.
They might be looking at:
Bolton, too hawkish
Giuliani, ditto according to Rand Paul; I do not know that much about it myself.
Romney...
So, while some folks don't like Mitt in that position, it could come down to, well, if not Mitt, whom? There might not be that many choices.
These are the important decisions, it is kind of amusing to see folks talking so much about SNL and fashion designers and so forth.
