The GOP is no place for a egoistical,narcissistic,fraud like Trump, weather he swore like a sailor or not.
When I was a young boy in the US Navy, at first I used foul language and then I noticed my Chief Petty Officer whom I admired expressed himself quite effectively without using any foul language because he had an adequate vocabulary to be authoritative and commanding. I realized my vocabulary was weak and inadequate and worked on learning to communicate without using foul language and have done so ever since.
Foul language is evidence of weak and adequate speaking skill. Richard Nixon was a poor speaker and used foul language habitually
Dennis Prager is right.
