Bernie supporters filed a lawsuit against the DNC for disenfranchising them. The DNC argued they operate as a private corporation and are free to pick whomever they want "over cigars in a back room".
> “There’s no right to not have your candidate disadvantaged or have another candidate advantaged. There’s no contractual obligation here . . . it’s not a situation where a promise has been made that is an enforceable promise,” Spiva said.
> The DNC is advancing the argument that any claims to be neutral and fair to all candidates were nothing but “political promises” and are unenforceable by law.
