She can't win the nomination with super-delegates and then win in November. This is why she was blocked from winning with them in 2008. Since she has attacked Sanders as disloyal to Obama, he may as well remind South Carolina she tried to do that. If she relies on superdelegates to be nominated, she surrenders the electability argument to Sanders. (in Debbie's defense, she's not the one who created super-delegates. Still, a Clinton loyalist shouldn't be chairwoman during this primary.)
Yeah, I don't think anyone who wants the Democratic party to win in November wants the nominee to win the primary just because of superdelegates.
