Since the DNC and the RNC are both private organizations, and they can allow or disallow anything they want. Bernie was certainly allowed to run for anything he wanted, but to be allowed to run on the Democratic ticket required approval by the DNC.
Then I suggest you encourage the DNC to say it in such a fashion, but they don't, yet another double standard. Better yet, be more courageous and blunt:
"We didn't want any competition for Hillary which is why we blocked Gabbard from the debates and blocked Lawrence Lessig from being able to run and outright stole from Sanders. In fact, even if polls show a candidate has 90% of the approval of the Democratic Party, we will simply choose who we want, because democratic processes do not matter (ironic I know considering the party name), what matters to us is that we know what is best for you and will choose accordingly".
No wonder they were trounced in 2016. Socialist, dynasty principles lost to liberty of vote. The very same principles which the RNC reluctantly accepted, and it sunk Jeb, the Establishment fave in favour of a businessman who was anti-establishment, focused on working to recover the harm done to America.
I encourage the RNC to say it in such fashion too, because they are a private organization with the same rules.
Which candidate do you think had 90% approval of the DNC and was not allowed to run?
I am using 90% as an example. If Bernie had such a number they still deny him the candidacy. It was clear the fix was in early when CNN showed all delegates to date and fully awarded Clinton EVERY super delegate, when in reality, in terms of voted delegates to date they were closer to neck and neck.
As for the RNC, clearly they didn't want Trump, the difference is they pitted him against 15 other candidates. He earned his spot and as much as there was big money and deceptive methods employed to undermine him, in the end they accepted the Will of their voting base. The Democrats clearly did not.
I've said it many times, Sanders and I are ideologically incompatible. Regardless, if the DNC had no intention of allowing the Will of the People decide their candidate, they shouldn't have allowed anyone to debate. They only did so for optics, to give the impression the DNC was somehow not an extension of Hillary and her International donors, and she would "stand up to any and all comers and debate her positions with pride and conviction".
Nothing was further from the truth. It was a scam, by all accounts. Peoples time and efforts wasted, with no legitimate opportunity to win, as if they were living in a dictatorship froth with the smoke and mirrors that accompany such a system. Thankfully, the strength of the greater American system balanced this overt abuse by electing the underdog and chastising the entitled. Sadly, to this day many see this defiance of the voters continuing with efforts to usurp the election results.
