I don't understand how people can defend superdelegates but hate gerrymandering and/or the electoral college.
It's all meant to disenfranchise the power of a vote and it's all done to keep the bullshit two party system we have rolling along.
Superdelegates are set up by private parties, and are meant to protect the party from guys like Trump from coming in and running on a ticket without sharing the platform of that ticket. They never go against the candidate with the most pledged delegates and I'll bet the GOP wishes they had a similar system in place right about now.
Gerrymandering is done at the state levels by the government and yes it is directly about picking constituents that favor entrenched candidates.
The electoral college may be "Undemocratic" but it has not ever once voted for a candidate without the majority of public vote.
The two party system is bullshit, but I'd say it's kept alive by political polarization among the voter base more than anything. Nothing is stopping anyone from starting a strong third party, they just haven't been successful in pulling people away from their party platforms. The blame lies with the voters
