"If anyone can identify what's wrong with America's busted engine, it's the woman who's had her head under the hood for 30 years."

I work for a US based company and have many friends from across the US.  I spoke with them many times throughout 2016.   Without question, both candidates were seen as  terrible choices.    From their point of view, Hillary had a huge amount of baggage starting with an exceptional amount of wealth amassed by two life-long public servants.  It included issues like the email server (and Bill's supposed chance meeting with the Attorney General on a private jet) that caused concern.  She was seen as a political insider and we all know there is something very wrong in Washington.   That 30 years under the hood was an albatross around her neck. 

She didn't seem to recognize the depth of her weaknesses.    Sexism played a role in her defeat, to be sure, but there was much, much more that was specific to her as a Candidate that caused the loss.
