Well, I'll grant you that Sanders could easily win the nomination if Clinton's army of superdelegates started evacuating en masse, but that doesn't seem particularly likely. As it stands, in order to make up the deficit, he needs to blow Clinton out of the water in every primary from here until the convention.
Sanders needs a mathematical perfect storm to pull this off, and even as an ardent supporter, I just don't see that happening.
Well, if Sanders starts leading the popular vote overall the super-delegates will mostly have to switch. This is very unlikely though. Sanders will need 10%+ leads in places like CA NY PA IL etc etc which does not look like in the cards even as it is possible he might get very narrow wins in those states.
