From a few years ago, but the data is interesting, and the prose makes me say, "I wish I wrote that."
Donald Trump’s grade level, on Day 986 of his Presidency, declined slightly from the first two analyses, dropping from a grade level of 4.6 to 4.5. In all three analyses, he consistently has the lowest score of all U.S. Presidents since Herbert Hoover, regardless of methodology or sample size.
