Trump has also said, and shown, that if sees a better idea than the one he’s proposed, he’s willing to change his mind - the mark of intelligence IMO. I see Trump as an intelligent man and hope he realizes that private citizens would be valuable to his administration, as they were with Reagan.
One can always hope.
I have no doubt that there will be private citizens serving in his administration-he’s already stated that. The question under discussion was his VP pick.
