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.
Not a chance in hell PDJT is going for Speaker. That would completely undermine his return to the White House, whenever that may be.
He doesn't have to run for soh. He can be nominated while golfing at Mar a Lago honestly.
