Even though Trump is a rich man, he's the first "common man" to be in the White House since Truman.
I.E. He has the typical American mindset.
Trump is the most out of touch President to ever occupy the White House
He is totally clueless on popular culture, movies, books, music and humor
He really does not know how to deal with people.....only how he wants others to deal with him
Common man?
Trump doesn't know how to ride a bike, change a car tire, change a diaper, cook a hamburger, fill his car with gas
