Billionaire Mark Cuban knows Donald Trump.
On this morning's Morning Joe, Cuban had some advice for Hillary Clinton: laugh, ridicule, belittle, and smirk.
"He's just going to throw jabs, trying to keep her on the defensive. She's got to smile. Literally every time he says something stupid, she's got to smile because that's what will drive him crazy. He goes nuts when somebody thinks he isn't smart. There is a reason why he always mentions where he went to school--to have his ego stroked. He doesn't have confidence in his own intellectual ability apparently, and so when you question that, even with a subtle smile, a little giggle, a little shake your head, he will go nuts. That's what I would tell her to do."
Cuban also said the time limitations of television always play to Trump's advantage:
"I know you guys have tried to reassert him back to the topic often, but I would get to the heart of the matter. 'Do you understand this question? And then I would ask a follow-up question: 'Do you know where Aleppo is? Do you know what the issues are? Do you know what's the history of this city and the conflict?'"
"If you stay with it, he will crumble. But the problem is, everybody gets to the point where you get frustrated. You have a script or a schedule to follow. And that makes it difficult for you to just keep banging on him. But that is what it's going to take."
