The uncanny prediction occurred in "Bart To The Future", an episode
revealing how the lives of its central characters could turn out.
It later referenced his real-life run for the presidency again last
year in a short clip called Trumptastic Voyage - though by this
stage his candidacy was more commonly expected.
Earlier this year Simpsons creator Matt Groening told The
Guardian they used Trump because he was "the most absurd
placeholder joke name that we could think of".
Dan Greaney, a long-time writer for the show, said it was a
"warning to America". He told The Hollywood Reporter : "That just seemed like the logical last stop before hitting bottom. It was pitched because it was consistent with the vision of America going insane."
