Markos says no, the superdelegates will not be bailing Bernie out.
Hillary Clinton will end the contest with the most pledged delegates, and it won’t even be close. It was closer in 2008—and it wasn’t close back then, either. Best case scenario for Sanders at this point is that he splits the delegates through the end of the contest, but he’ll likely lose even more ground. So whether Clinton needs the superdelegates to get her a majority of all delegates is irrelevant. Obama needed the supers to get him a majority, too, and no one called it a “contested convention” because that would’ve been stupid and asinine.
[...] It’s undemocratic for a party elite to ignore the will of the voters and substitute their preferences for that of the party base. It was bullshit when Clinton made these arguments in 2008, and it’s bullshit today [when Sanders makes them]. You can rail against the establishment all cycle and sue the Democratic Party. It was good politics! It won him lots of votes! But then don’t expect that very same establishment to bail you out. If you go to war against them, you must beat them on the electoral battlefield. And it can be done! Because Barack Obama did it in 2008. And if the supers wouldn’t bail out Clinton that year, when Clinton was on the losing end, why would they turn on her this year, when she’s on the winning end?
Bernie’s insistence that the process is “rigged” and that he expects a contested convention are exasperating, especially when you consider, and Bernie admits himself, he will need the "rigged" super-delegates to make the convention contested. And it is all the more exasperating because it would be overwhelmingly anti-democratic.
