Peter Dreier: “Anyone who feels compelled to boast how smart he is clearly suffers from a profound insecurity about his intelligence and accomplishments. In Trump’s case, he has good reason to have doubts.”

“A linguistic analysis by Politico found that Trump speaks at a third-grade level. A study by researchers at Carnegie-Mellon University compared last year’s Republican and Democratic presidential candidates in terms of their vocabulary and grammar. Trump scored at a fifth-grade level, the lowest of all the candidates.”
