Love him or hate him, there's a certain quality about Donald Trump's statements and proposed policies that can feel like fantasy. Specifically, they can feel like the kind of fantasy that makes up a world like Game of Thrones' Westeros.
So it only makes sense that someone has taken Trump's words (and face) an put them directly into the hit HBO show. With some skillful editing, you would think that Trump's talk about building a giant wall and keeping people out of a country was always meant to be part of George R.R. Martin's plot.
