Are there any recent books that lay out for the general public not only what the constitutional duties of the president are, but what the entire range of activities a modern chief executive must engage in and what skills are required to perform them successfully? Clearly messaging and management skills are important, and clearly Trump is completely lacking in both.
It would be nice if voters could go down a checklist and hold each candidate up to scrutiny in a systematic and complete way.
Our candidate debates are completely lacking from this point of view. They are mishmashes of questions, one-upmanship, and soundbites. They are gameshows and entertainment. They emphasize out-of-context policy details over competence and character.
We certainly don’t make hiring decisions in academia this way (my only hiring committee experience).
