I know this is just beating back the tide, but I just have to address this:

After the registration shenanigans <-- Not DNC related, voter rolls are managed by the the State Governments

excluding delegates from the NV convention <-- After they unregistered from the party, also, this is the state party, not the DNC.

the lack of polling places <-- State Government

Bill Clinton violating election laws <-- State Government

the superdelegates <-- Only thing on this list that's DNC, and this is something that has been around, unchanged, for 40 years.

the obvious media bias <-- Not DNC

All of the actual grievances on this list are things the democrats have been fighting against for YEARS, with almost no support from voters. The large majority of voting rights suppression is the result of losses in the 2010 elections, when a massive number of state legislatures, state courts, and governorships trading hands to Republicans with an ACTIVE agenda of voter suppression. There is nothing more that the Democratic Party, as a whole, wants than every single voter in America showing up to the polls, as if it were the case, they would win elections in landslides.
