I am not well educated on Hillary’s downsides. i.e. when I see people saying “… I voted for Trump because at least it’s not Hillary”, or “I did not want Hillary in the office”.

What did Hillary do exactly that cost her the vote and the presidency? Was it solely the Benghazi and “emails”?

Answer:

Contrary to the other answers here it is very simple, and it had nothing to do with Hillary’s email escapades or Benghazi.

She didn’t listen to Bill, who is by far a better politician.

Since 1992 Democrats have held a solid "blue wall" of Great Lakes battleground states: Wisconsin, Michigan, and Pennsylvania. In 2016 those states represented forty-six electoral votes.

The story is being told that after the Wisconsin primary Bill’s advice was, “Yah all, should be payin’ more attention to these workin’ folks.”

During the campaign, Bill Clinton felt that he was ignored by Hillary's top advisers when he urged them to make the economy the centerpiece of her campaign. He repeatedly urged them to connect with the people who had been left behind by the revolutions in technology and globalization."

Bill said that constantly attacking Trump for his defects made Hillary's staff and the media happy, but that it wasn't a message that resonated with voters, especially in the rust belt," the source explained. "Bill always campaigned as a guy who felt your pain, but Hillary came across as someone who was pissed off at her enemy [Trump], not someone who was reaching out and trying to make life better for the white working class."

Hillary’s staff laughed at him. (I’m assuming behind his back.) Trump flipped Wisconsin, Pennsylvania, and Michigan—the margin of victory.

Note: After the primary Hillary never set foot in Wisconsin again.
