One demographic of women voted for Trump = white non college educated women, dragging the total number of white women, college and noncollege up to a bare majority of 54% for Trump, basically the same percentage of white women voted voted during both Obama campaigns (56% and 55% respectively)
How white women voted was an entirely predictable phenom. Hillary's campaign planned for it, and the white women's vote story is utterly boring (until this year at least -- I have hopes for the midterms), unless you have an agenda that involves blaming white women.
The Democrats haven't carried a majority of whites, male or female, in decades.
However, white men preferred Trump over Hillary by 12 points, a significantly larger percent than voted for Romney over Obama (7 points). It's also the widest gender (sic) gap since 1972.
All this stuff was nicely and promptly broken down by Pew Research after the election, but a few pundits took it upon themselves to explain it as if the white female vote was something new and then it took root on Twitter.
If you look at the real numbers, not only are white men responsible for Trump, but the thing strongly smells of misogyny.
But hey, who wants to be confronted when there's a women nearby to blame.
