Hillary Clinton surrogate Ed Rendell has a warning for Bernie Sanders supporters: you better behave in Philadelphia. Resistance is futile.

The former Pennsylvania governor said:

“I think it’s gonna be a great convention, but of course the key to it is the Sanders people. Bernie’s gonna have his name placed in nomination; we’re gonna have a roll call; there’s gonna be a demonstration in support of Bernie; he’s gonna lose the roll call.

“His supporters have to behave and not cause trouble. And I think they will, and I think Sen. Sanders will send them a strong message.”
