Acne occurs in dry climates and humid climates.  The interesting study is not the acne, but rather, the climates causing the acne.  We've never had such a climate in D.C. as a big businessman at the helm.  We've ever had poor politicians needing office to get wealth, lawyers with visions of grandeur, minorities with cultural axes to grind, and rich kids raised in politics.  We've never had an insecure consummate big businessman who needs nothing from anybody...whose business success allowed him to think that he could tell anybody off even before becoming the most politically and militarily powerful man in the world.  Historically, we've only had mealy brash politicians ascending to the White House to become greater mealy brash politicians.  We just have a way different climate flaring up the same old acne toward the same irresistible tendency to pop that pimple head.
