Misogyny probably did play a small role, just as Trump probably lost votes for his questionable taste in clothes.  I haven't read the book, but from where I sit Hillary lost because her vision was about as fresh as a week old baguette.

Clinton was too entrenched in the Washington machine, and her husband had steered the Democrats on a slow drift to the right that she and Obama did little to correct.  What's more, she badly mishandled the health care file and was an ineffective secretary of state.

If she hadn't seemed so out of touch with the concerns of Americans during the election she might have overcome those handicaps.  But the 20-odd apologies Renzetti refers to in the book don't make up for a bad campaign based on tired ideology, and nor do they prove that misogyny played anything but third fiddle in her defeat.
