I can’t understand how commentators like Dr. Myron Kuropas can still support Donald Trump. In his January 19 column, he admits that in 2016 he found Mr. Trump to be a “narcissistic, vulgar oaf.” Perhaps Dr. Kuropas’s views have changed, but many of my fellow Americans find Trump to be even more vulgar and morally objectionable. Mr. Trump is a shameless admirer of Vladimir Putin. He openly invited Russia to interfere in our electoral system. Mr. Trump withheld aid from Ukraine, apparently to pressure the Zelenskyy government to dig up dirt and concoct scandals on Mr. Trump’s political opponent.
