It seems to me when the question comes up, it's usually more a question of what the superdelegates are likely to do, with the majority of people expressing the opinion that they are likely to go with the leader in pledged delegates.
Even Sanders agrees on that:
"I think it is probably the case that the candidate who has the most pledged delegates is going to be the candidate, but there are other factors. And the other factors will be the strength of each of us in taking on the Republican candidate...."
The folks I take issue with are those who declare that the superdelegates "must" or "should" always vote for the candidate who's ahead in pledged delegates. That's a ridiculous position. Why do you think the Democratic Party decided to add superdelegates? They had "buyer's regret" about Carter and decided to add superdelegates so they had "people who know better" in place to overrule when they believe the voters have made a losing choice.
I don't think we should have superdelegates at all. But if you accept that we DO have them, you have to accept what their role is, and let go of the silly notion that they "should always" vote for the pledged delegate leader. That is simply not what they are there for.
