The fact is that the majority of men who hold post bachelors degrees are white. This plays to Hillary's biggest weakness, and Trumps biggest constituency, white men.

its ridiculous....

If even the post-grads prefer Trump, there is really something wrong.

I realize that their loss of monopoly on the presidency is hard on their ego...but seriously preferring Trump?http://presidentialgenderwatch.org/polls/womens-vote-watch/presidential-polling-data/

Women tend (in my experience) to have equal or greater representation in grad programs for fields which traditionally skew to the left (the humanities, education, library science, nursing, for example), while men are overrepresented in programs that likely trend more conservative (mba, other business) or fields like engineering.

That could play a role.

There might even be some men in technical fields who believe that their female co-workers aren't contributing as much, so there could be some resentment about talk of "equal pay for equal work" when measurement of work would be nearly impossible to measure by a distant bureaucratic overseer. I'm mostly speculating.
