There was an honorable way for a member of the DNC to support Sanders or Clinton. For example, Tulsi Gabbard (Rep. from Hawaii) resigned from the DNC and then endorsed Sanders and campaigned for him. And there may have been members of the DNC who wished to support Clinton and resigned from the DNC to do so. I can't name one. Can anybody? Surely, both the DNC and RNC set up the rules to provide what they perceive as stability: closed primaries, winner-take-all states, super delegates. I think that when Florida's RNC primary was made winner-take-all, the party thought that Jeb! could take his own state. But please, there is a distinction between making the rules and breaking them. I am not a lawyer, but I like to think that the rules become a legally binding contract between the DNC, the RNC, and their donors.
