Since you're so smart why don't you tell us how people get selected for cabinet positions?
When you get high enough in any profession...even the military...if you want to advance higher you have to play politics...so lets just say that's a give in this instance or for any cabinet position.
IN some cases you get a cabinet position because of how much money you've raised for the person now occupying the WH be they Dem or Repub...some people...like Mark Levin lets say...stump and campaign for the eventual president starting when they are 18. Now I will admit in Levin's case he didn't get a cabinet level position...but Chief of Staff to the AG is pretty darn close.
Some people get the positions because they are career government employees who work their way up.
In this case...IMHO...this was Trump using a friendship/association made in the board room to give someone with global connections the SecState position.
It wasn't to appease any fans of Rex. Most people had never heard of him before the appointment.
