He’s lost his mojo.....
I’m watching the re-run on Fox and his voice sounds as if he was screaming at the top of his lungs earlier in the day. He must have had a shouting match with Michelle losing some of his voice. It was also clearly obvious that he was jumping from one sentence to another rushing through the lines on the teleprompter. The text must have been moving too fast for him. This explains why Krauthammer said the speech was was disjointed.
