One of the tricks Donald Trump pulls for appealing to the lowest common denominator of the Republican constituency is as simple as keeping the words he says simple.

From Politico:

Trump resists multisyllabic words and complex, writerly sentence constructions when speaking extemporaneously in a debate, at a news conference or in an interview. He prefers to link short, blocky words into other short, blocky words to create short blocky sentences that he then stacks into short blocky paragraphs…

Run through the Flesch-Kincaid grade-level test, his text of responses score at the 4th-grade reading level. For Trump, that’s actually pretty advanced. All the other candidates rated higher, with Ted Cruz earning 9th-grade status. Ben Carson, Mike Huckabee, and Scott Walker scored at the 8th-grade level. John Kasich, the next-lowest after Trump, got a 5th-grade score.

Trump’s low grade at the debates wasn’t a fluke. His comments from an August 11 news conference in Michigan earned only a 3rd-grade score.
