Trump’s effective communication

This seemingly normal event, the election of a new President in the USA, has actually falsified a whole array of tenets generally viewed as valid in public speaking.
How can it be that an inarticulate candidate with a middle school English has won against a fully educated Hillary Clinton? She was coached in body language, was trained in public speaking, probably also in acting. Did her coaches get everything wrong? What are we missing? Is “effective” communication really not that effective after all?
