Its going to be very dangerous for the party. Even if they are technically following the rules, if its clear they blocked Sanders by manipulation it will destroy the party.This not how I interpreted it. The rules of plurality in the past with Al Gore, Obama and Clinton did not have enough delegates from the primary to win prior to the election. The superdelegates placed them over the 1991 delegates. It puts more power in the hands of the convention committee members and allows the option for manipulation.
Many of the committees chosen are known non Sanders supporters on record and some direct affiliations with other candidates and their campaigns. Which a few weeks ago is a reason I said that Bernie Sanders will not be the nominee. A brokered convention will be the tool that party elites can stop Sanders.
This allegiances or alliances can appear as blatant attempts as sabotaging and appear as elitist.
