It’s been a tough year for political prognosticators. First, almost all of them told us that Donald Trump’s candidacy would be collapsing by now. Instead, the latest CNN/ORC poll shows that he is ahead of his closest Republican rival by 2-to-1.

Now, one begins to wonder whether the commentariat is also dead wrong about women voters.

Take the most obvious case: Hillary Clinton. Conventional wisdom has held that she would be virtually bullet-proof among a vast number of women who fervently want the first African-American president to be succeeded by the first female president. Just as important, Clinton has devoted much of her professional life to championing the causes of women and children.
