It looks like Sanders is taking Weaver’s lead and not Tad Devine’s, to put it mildly. He’s making the case against closed primaries and more or less explicitly making the case that Super Delegates should choose him to be the nominee even if he’s behind in pledged delegates because he runs better against Donald Trump.
That said, there were no real attacks on Hillary Clinton. It seemed like a mix of recognition of the writing on the wall along with a defiant insistence that his campaign should get the nomination.
