As Trump was accusing CNN of being unfair by forcing candidates to react to his positions, Bush chimed in: "The simple fact is that if you think this is tough and you are not being treated fairly, imagine what is going to be like dealing with Putin or dealing with President Xi or dealing with the Islamic terrorism that exists," Bush said."This is a tough business to run for president."

Trump interrupted multiple times and nodded his head saying. "Alright, alright. I know you are a tough guy, Jeb. I know. You are really tough."

"You are never going to be president of the United States by insulting your way to the presidency," Bush fired back.

"Let's see I am at 42 and you are at 3, so far I am doing better," Trump said, referring to polling numbers. "You know you started over here, Jeb. You keep moving further and further. Pretty soon you are going to be off the end."
