For my 2 cents:
Sarah Palin DOE
John Bolton SOS
Rudy Guiliani AG
I don’t have a name for the DOD but it should be a General Patton type; someone who understands what the military is for and is not afraid to act accordingly.
Palin would never take a cabinet post. It would be low profile and she could not make money at it.
She will fade into obscurity.
