I anticipate a solid cabinet but not, necessarily, the folks named in the OP as “possibles.”
My guess is that a guy like Elon Musk wouldn’t want to accept an actual government post since that could hobble his abilities to do business.
Judge Cannon may be left in place for a while until an opening on the SCOTUS.
Marco Rubio could get a position but only to the extent that his absence from the Senate doesn’t interfere with Reump’s plans.
Vivek may get a position. Not sure he is Homeland material.
Bongino is probably not gonna want to lose out on his gravy train commentator niche.
However, there is a concept we all heard about back in our school days: a kitchen cabinet. Unofficial but trusted and valuable advisors.
For now, to wrestle against the deep state elements in the State Department and the DOJ, President Trump will need experienced and highly capable folks in those positions.
This will be fun to watch as it starts to come together.
