Perfect 20-20 hindsight.
Moody's tweet says that Ben Carson will not go to New Hampshire or South Carolina. Those are the locations of the next primaries. If Carson was not going to show up for the next two primaries, what would be the most likely explanation?

Why is Ted apologizing?? Because he knows he screwed up.

“I’ll tell you what it tells me,” Carson added. “It tells me a lot about character.”
