Superdelegates are a matter of internal party organisation. The party still has to go through a real election, whoever's chosen.

(It is very weird that the internal politics and internal elections of US political parties seem to be a public matter; open primaries are unheard of in most of the rest of the world.)

It's a lot more important with a 2 party system. If one party's administration gets almost 20% of the total primary votes, that's a pretty heavy thumb on the scale. We typically only get 2 real choices: red or blue.
