A pretty swift and concise 'no'. I like it. I wonder how furiously Bernard's team is typing up his response to this and what if anything he will do to follow up on his convention threats.
For people saying to give him what he wants; I don't agree. For a reasonable candidate with reasonable demands I could see giving an inch here or there for their support and backing. But I don't believe Bernard is bargaining in good faith. I think every little bit he gets he's going to ask for more and more and more.
Even though the concessions are meaningless, just ask Trump, this is how you win at making deals. You get your opponent to give you something small and then you ramp up. This works with everything, ask someone to loan you a dollar one day and they are more likely to loan you $5 next week. They are invested in you and are waiting for you to pay off sort of speak.
So the DNC 'invests' in Bernard, offering him meaningless concessions in the hope it quells his rhetoric; then he starts asking for more. Well since we already gave him this, and this is small too, okay. Then he keeps ramping it up. You look at what you've already given him and it starts adding up, and you look a little foolish to not give him the next thing because again you've already given him X and Y, what's the harm in giving him Z as well?
This is already happening. DNC gave him an unprecedented amount of say at the convention, and now he's asking for even more. So let's say they drop the two guys he has a problem with and you pick two new ones. Well suddenly he's got a problem with them too, but don't worry, he's got a list of names that would fit the bill that he feels is 'fair'. So just pick one of them and he'll be happy. Oh except wait, this other person seems a little problematic. Oh and about this party platform, don't think it goes far enough. Oh how about we add this to the party platform as well. And on and on. Trust me, with guys like Bernard it never ends. He's never going to be satisfied until he's in complete control.
