I do solemnly swear (or affirm) that I will faithfully execute the Office of President of the United States, and will to the best of my ability, preserve, protect and defend the Constitution of the United States.
Who knows, understands in depth, has been preserving, protecting and defending the Constitution the most among the candidates?
If the candidates don't have a clue about the US Constitution which is the foundation of this country, how are they going to execute the thing that they take the oath to do faithfully?

The art of making deals with other countries is called diplomacy. It is carried out by professional diplomats prior to endorsement by national politicians.
In the US, the Secretary of State is the top international negotiator/diplomat. Donald Trump is a master negotiator and would therefore be ideal for Secretary of State, head of the diplomatic corps.
Just look at the Iran deal - it was Secretary of State John Kerry who spent long hours and drove a 'hard bargain' with the Iranians.
