It just ended.

He used teleprompters and hardly went off script.
When heckled, many times, he didn't make faces or lose composure. He just waited it out. Except for a comment about Sander's protestors.

He talked about her record in New York. And the difference in their economic policy.

It looked like a very different Trump, at least to me.
