Trump is greatly loved by his many supporters, and it shows in the many ways unique to our times that you have noted, and many other ways as well. We are living in a media age, that has brought his image and words to people daily for many years.
But in terms of “the history of the United States”, we cannot slight George Washington, who was one of the greatest men of world history, very greatly esteemed and respected to the heights of people's ability in those pre-electronic times.
It is very difficult to compare George Washington and Trump’s popularity. Donald Trump is not only loved in the United States, he’s loved all over the world. The population of the USA today is, obviously, nothing like it was during Washington’s day.
