Hate to say this, but our best choice for SecState is John Bolton. He leans establishment, but his credentials and knowledge make him a good fit. What he would need from Trump is direction on how to clean up State and he could do it.
If you do not decimate the state department and rebuild it as your first and foremost priority, then it doesn’t matter who runs it. Both Clinton and Kerry thought state meant traveling the world, eating good food, meeting leaders and having photo opportunities. State is our policies for people entering this country, our representation outside the country and negotiating on how protecting America benefits their countries. Bolton could do that. Not sure who else can.
