Superdelegates are the primary tool that the DNC used to exert influence over primaries. They’ve only ever once voted against the voter consensus, but they pledge full support early, which is then used by the media to grossly misrepresent candidate popularity. Mob mentality causes voters to pile behind the leading candidates, and thus the outcome of the primaries can be manipulated through use of super delegates. They abused this mechanism so heavily against Bernie that sweeping changes were made to the way that super delegates operate to avoid torch and pitchforks from an enraged constituency.

There, I explained it to you in a very summarized form, even though I didn’t want to.
