Optics.
Perhaps it is the plan to make DJT speaker of the house. The optics would not be as good if 45 opposed McCarthy because he wanted to be speaker of the house.
Now Trump can get a nomination without that fight against McCarthy.
After all, McCarthy is the first failed speaker vote in 100 years. We all know Trump's world consists of Longshots.
Ive watched Donald Trump since the early 80s and have learned enough to know that there is a reason why he went against the consensus among his base. There is a plan, a countermove. That his endorsement of McCarthy and the votes today would maneuver the enemy into a position of his choosing. That he has chosen the field and prepared it in a manner of his choosing. Sun Tzu, Art of War shit. Game Theory. What brilliant Generals do.
Ive learned not to doubt the man. As he likes to say "Lets see what happens".
