Data science tricks for understanding Trump’s rhetorical appeal

hitler-trump-compare

I pulled down a huge collection of Donald Trump’s speeches and ran them through the TFIDF algorithm using python’s scikit.learn toolkit. Here are the most common Trump phrases (slightly edited to be more readable):

For kicks, here are the most common phrases of similar length in Hitler’s speeches from 1921 through 1941. Trump’s rhetoric has been compared to Hitler’s style, but the only similarities seem to be in themes of “us vs them” and presenting all solutions as being either one thing or another (no nuance or shades of gray):

Trump’s speeches are blanketed with promises. He promises to build a wall, take care of [insert special interest group], and bring glory to his country. His ideas are simple to grasp and repeat, and leave ample room for the audience to fill in the details as he/she wishes.

Hitler, in contrast, tries to lay out logical arguments why his view is the right one. He uses longer sentences and bigger words, connected in complex thoughts. He couches his arguments as a battle between the German people (and the state being, by extension, the will of the people) against the rest of the world. Both present their country as standing against the bullying world, even though both nations are arguably among the most powerful in the world.

Surprises

One thing missing from both Trump’s and Hitler’s rhetoric are mentions of Muslims or Jews, respectively. They’re there, but not explicit, not repeated as often as other promises or arguments about national greatness. Computers don’t catch the subtext in speeches, and that is where the language of racial/ethnic divisiveness lives.
