Thanks for the link. This quote goes far to answer Gary Crum's question:

"Nationally, Clinton picked up 54 percent of women voters compared with Trump’s mere 42 percent. But Trump outperformed Clinton among white women, winning 53 percent of voters in that demographic. Drilling down further, he beat Clinton among white women without college degrees by 27 points. In the three states that decided the election — Wisconsin, Pennsylvania, and Michigan — that margin was enough to send Trump to the White House."

In short: uneducated and white.
