To you and the others who seem to think it has no effect. Just look at the confusion in this thread among pretty well informed voters. You think seeing after the first primary, news sites reporting delegate totals with superdelegates showing clinton having an insurmountable lead, even though you and everyone else immediately mentions that they still can vote whatever way, has no affect on voters? Especially when most voters don't understand superdelegates and receive no explanation from news outlets? You don't think it enforces the narrative that Clinton is the inevitable candidate for the party and Sanders is a fringe candidate w no chance?
I mean, if you guys don't see that, I don't know what to tell you. I'm not saying that DECIDED this primary, but to me it's pretty obvious that those numbers affect people, especially the undecided and independent voters that would be more likely to vote for a candidate like sanders. Feeding select information is like THE way you would control or manage narrative.
No, that shouldn't be the job of the superdelegates, but that's why they were created. It's hard to have this conversation where one reply will be claiming Sanders supporters are ignorant of the history of superdelegates then have other people come back and ponder what the point of superdelegates are.
You're right, there's a whole host of ways superdelegates could or should vote, the fact is that they are essentially a super vote. They vote for their own reasons, whatever they may be, whatever the intention of giving them that super vote might have been. But whatever the reason, they're a person who has the voting power of a large sum of people. That's... well, I and other people don't like it I guess is the point.
