Huffington: If Trump Can’t Deal with GOP, How Can He Make Deals with Mexico or Putin?

If Donald Trump can't even manage deals within his own party like Ted Cruz is doing, how can he cut tough deals with Mexico and Putin, Arianna Huffington asked today. 

"One interesting thing about Trump here: He always talks as though every problem can be solved by making a great deal, whether it’s the wall with Mexico, the relationship with Putin, and in the area where he’s supposed to be a master at deal-making, he’s failing," Huffington said today on "Morning Joe." "He’s basically failing to make the kind of deals that Cruz is making that gets him all these extra delegates." 

"If he can’t make a deal with his own party," she asked, "How can we expect him to make a deal with Mexico to have them pay for the wall, or Putin or all the other deals which he’s going to be making?"
