Do you believe that the unelected bureaucrats, not accountable to voters, holding 15% of the voting power is just something that is in line with the way one would imagine an ideal democracy in a primary?
Certainly not a perfect one, no, but that is exactly how the process works, so I don't see any pretense.
I voted for Bernie Sanders but pop over to the Wikipedia page and you'll see that he lost the popular vote by 3 million and change in an election 30 million people participated in. Not the narrowest of margins. In a perfect democracy, he'd have also lost. The superdelegate system was irrelevant in this case.
