Yeah, that picture sums it up pretty well.
What this guy doesn’t get is that Bernie getting the nom would require the Dem Superdelegates to defect from Hillary. The Superdelegates were established to prevent a non-establishment candidate, like Bernie, from getting the nomination.
Hillary has the Superdelegates locked up at this point. Which means she only needs to capture around 37% of the regular delegates to get the nomination.
This doesn’t factor in two unknowns tho. First, how the Bernie folks react if their guy gets a majority of the regular delegates, but still loses to Hillary thanks to the Supers. Second, what happens to the Supers if Hillary gets indicted and loses the Supers because they flee and/or she drops out.
