"You know how proud we are of the Sanders campaign ... [View all]
... and what we think of you at the DNC. But now there are people who want you out. You've had months in this primary, Bernie. Longer than anyone expected."
"Get out... How can I do that?"
"At your special press conference. Some people feel this press conference should be used to announce your retirement. When you first entered this contest, here at the DNC, we saw it as a good thing. Now the Executive Directorate wants a change. The program is scheduled, the world is waiting, so this does seem the perfect time."
"The people, they depend on me."
"Bernie, let's think this through together. You know how the electoral process serves us. It has a definite social purpose. Nations are bankrupt, gone. A few of us making decisions on a global basis for the common good. Corporate society takes care of everything. And all it asks of anyone, all it has ever asked of anyone ever, is not to interfere with management decisions. So, now you're going to retire. That shouldn't be too hard for you. Stupid game, after all. Awful game. You ought to be glad to be out of it."
"I do know I can get some concessions and I want 'em."
"You're bargaining for the right to stay in a horrible social spectacle. It has its purposes. You've served those purposes brilliantly. Why argue when you can quit?"
"I'll see you in Philadelphia."
"You can be made to quit! You can be forced!"
"You can't make me quit!"
"Don't tell me I can't. Don't ever say that! I can! You can be stopped!"
