Wilding v. DNC is the court case where the DNC admitted that they don't have to abide by the primaries because they are a private entity and can nominate whomever they want.
There used to be transcripts of this everywhere.
I'm all for everyone voting for the "lesser of two evils". I think everyone should go vote in the primaries. I also think everyone should pay very close attention to the DNC bureaucracy and minor rule changes and what everyone around them is saying and voting for.
Because seeing everything up close, in a world full of lies and deception, is what most people need to understand the truth. So they can make the hard decisions they will need to make.
