Cruz Slams Trump: People Are Not Interested in Temper Tantrums

"Donald Trump is very rattled right now. He told the entire world he was going to win Iowa. And then he didn't win. And his reaction is, he got very angry. You know, he said, how stupid could the people of Iowa be? I assume the next question he's going to ask is how stupid can the people of New Hampshire be? (Applause) You know, my view of it is, this is a job. And I don't think people are interested in temper tantrums. I don't think people are interested in insults and attacks."
