The lowest common denominator
One of the classic philosophers, (perhaps Plato?) wrote about our "ideals". For example, when you envision a horse, you do not think of an old sway-back mule, but a beautiful stallion. When we think of a house, we do think of an old run-down shack, but something more beautiful. Those are higher "ideals" of reality.
With Donald Trump in the White House, he does not represent our higher ideals, in my opinion.
He would prefer the friendship of tyrants to the friendship of honorable men and women. He is more likely to befriend a criminal over the law-abiding citizen. He prefers the shady and crooked path over the straight and narrow.
He prefers to look at the negative instead of the positive. He prefers to
criticize rather than compliment. He prefers to divide rather than unite.
He seeks to take America lower. He seeks to destroy the ideal of community and democracy. He is the lowest common denominator to all of our ideals about becoming a better nation.
