Superdelegates in both parties serve the same purpose. It helps ensure that the nominee is at least partially hand picked by the party.
Before there were superdelegates, there was the possibility that the national voting could actually pick someone who just wouldn't be a real contender vs whomever was running in the rival party. Now, the party has the last say, if you will, to overturn a national vote.
Its not really anti-democratic either. All other parties simply choose a nominee. The only part of the election that is supposed to be democratic is the November election between all parties for President. Who the parties select as their candidate has historically been done behind closed doors.
In all reality, the actual presidential election is not done in a true democratic manner. This was proven when Bush won in 2000. Popular vote was overturned by the Supreme Court. It has also happened a couple other times.
As for the nominee process, it is fine the way it is. However, the actual presidential election should be reformed to be solely based on popular vote.
