In a way, right back to the 80s, Trump was the embodiment of a certain type of New York City person: the brash, vulgar, outer-borough outsider who wants to conquer Manhattan. If there's ever a Trump biopic worth a s**t, it will constantly refer back to an establishing shot of Trump looking longingly out a window in Queens towards Manhattan with his father Fred saying something along the lines of "we stay in our borough." In a lot of ways, Trump's entire life goal was to become a Manhattan socialite, but instead he became a Manhattan laughingstock and punchline, so he decided to play that role to the hilt instead. Trump's entire early social circle (including Roy Cohn!!!!!!!!!!!!!!!!!!!!) were fellow bitter, slighted outcasts who were thwarted in their route into Manhattan society.
Sounds eerily similar to Arron Banks, the millionaire bankroller of UKIP and Leave.
