He's definitely legendary. Assuming the truth of the last 8 years is told as it really was, he will go down in history as the most interesting, liked, funny, egoistical, stubborn, brazen, and determined president ever (it will help that he will also be the most recent in living memory post-civil/global war in whatever new state comes from the ashes). Like Teddy Roosevelt, Dwight Eisenhower, Abraham Lincoln, JFK and Bill Clinton all bundled together.
