I will say Hillary is known for dirty tricks but there is no legit way to win the nomination.
The legit way is to use the Rats’ superdelegate structure to her advantage. This is the purpose of superdelegates-—to allow the party elites to control the nomination-—indeed, the TICKET as a whole-—in cases where they think the electorate is handing them a goose egg (such as one named McGovern, et al.).
The closer the race is, the more legitimate it is for each candidate to make various arguments that the superdelegates ought to support them.
Since there are arguments on both sides, and since each candidate appeals to certain voter blocs, it’s likely the superdelegates will say “let’s have a compromise ticket with BOTH candidates on the ticket” and make that a condition for each candidate to get the other candidate’s superdelegates.
