Democrat Convention Chairman Ed Rendell told radio host John Catsimatidis, Bernie supporters better “behave” once he loses the nomination to super delegates at the Democrat convention in Philadelphia.

The Hill reported:

During a radio interview with John Catsimatidis, Ed Rendell, a former Pennsylvania governor and Democratic National Committee chairman, laid out his vision for how the convention would play out.

“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,” he said. “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.”
