You cannot believe he is seriously thinking they might promise to endorse him/not endorse him if he appears/refuses to appear at their structurally untenable and irrelevant debate.

Where did I write that nonsense or think I believe it..?

If you don't realize this is a guy who cannot help but announce as loudly as possible precisely what is on his mind, there is no way anyone can help you.

Yeah, I'm pretty helpless when it comes to thinking for myself.../ S

It's right at the top in my reply post to your original one. I italicized it for you after copying it from your post.

Figure of speech employed to emphasize that I think Trump says precisely what's on his mind and cannot even help himself if he tried. That is why I think your reading into this that he is actually trying to gain an endorsement is reading much more into it than you need to.
