President Trump has no political background, so hasn't learned the art of politics, whereas those who have, have learned how to manipulate, play to the popular gallery and generally appear to be something, and someone that they in fact are not! President Reagan as a one time actor as well as a governor of California, knew this and played the part perfectly, The Kennedy's, Clinton's, Bush, to name a few also smiled and charmed their ambitious way to their advantage. Obama too was full of charm and bonhomme, while quietly bombing Syria, and, among other things compiling lists of undesirable countries, but not making a song and dance about it, a failure on the part of Trump. (given time,he'll no doubt learn to be as devious as the rest of them) Never judge a book by its cover, the truth of what you see can be very different.
