...I don’t get where they say he is so disliked by women."
Let me cheer you :)
A minor detail was most probably omitted. I would say it's a 69% disapproval rating among the democrats. It's democrat women who hate Trump. otoh, they hate everything.
If you look at exit polling for most of the primaries so far, Trump has some more support among men, but it’s pretty even. Wisconsin for instance his support between men and women was very even.
