DNC was worried that Bernie would be nominated.

Super delegates are undemocratic, and always have been. How does the party of 'democracy' get away with this? The GOP has never used them and always just let its voters vote. When the voters chose Trump despite the leaderships hatred of them, they all stepped aside. Are they perfect... of course not? But compared to the democrats, they've always stood by their voters.

Yep, the DNC has lacked the self-awareness in these past few years to gaze within and cull the cruft that 100% of their voter base hate. Superdelegates need to go. They're this generation's Korematsu (as in they are still active while people would rightfully think they're gone). I feel confident that superdelegates will come back to bite the DNC decades down the line.

In fairness, they actually did change the rules around them after 2016 but stopped short of removing them.

I hope they get rid of them!

Yep, I think that is the ultimate reason. The GOP party ends up listening to their voters and the Democratic party does not

GOP has also been captured by a B-list celebrity whose brand is rich, asshole misogynist.
