Put it this way:
a) Donald Trump has taken and bought failing businesses---and turned each one into corporate powerhouses--many on a global level.
b) Donald Trump has successfully entered into business meeting negotiations with foreign business leaders world-wide--people of greatly diverse social cultures, backgrounds and beliefs, and from those meetings, not only did everyone get along--but Donald Trump achieved full cooperative bipartisanship BEFORE entering the Presidency office.
c) Donald Trump, through his hard work, has earned and maintains multi-billionaire status. The man knows how to financially recover failing businesses---and return them to full financial health. Let the man do what is needed to UNDO Obama s and Bush, Jr s incompetent damage.
Given all three points, your answer is: Yes--President Trump IS quite smart.
