No question that there were more than  a few wingnuts who used her gender to attack.  But I think Hillary's real problem is that she was the ultimate personification of the swamp that Trump vowed to drain. I believe that most folks who voted for Trump were voting for change rather than the man himself.  The yahoos at his rallies wearing those disgusting shirts were certainly the minority, and their vitriol wasn't solely aimed at her -- the noose, journalist, some assembly required shirt was the most offensive one I saw.

 I thought Hillary lost some credibility when she said misogyny was a factor -- even if true, it left a sore loser impression.  She has redeemed herself somewhat by starting a political group to oppose the less savoury Trump policies.  It takes courage not to just shut up and go away.
