I suspect He’s doing it for himself.

More or less. It seems he cares about the country but relatively not enough to dictate and/or prioritize his actions accordingly.

Even after they stabbed him in the back, because in spite of their epic ratings tank they still have better market reach than news max and OAN put together.

Don't forget the traitorous Zionists running fake news media were already ready to commercially suffer losing essentially half of their viewership in return for kickbacks in one form or another from the globalists in their roles of constantly launching subversive coups only the latest of which was the election stealing. Therefore, they were likely more than thrilled that he kept coming back to them even after they threw him under the bus and the country over the cliff. Ultimately though, neither they nor Trump suffered. It's American citizens, including libtards, who pay the price.
