They still refuse to accept just how weak a candidate Hillary was, and what a horrible campaign she ran. Indeed she barely campaigned at all, attended more private fundraisers than public campaign stops, refused to campaign in some states and didn’t defend others, and then went out and called tens of millions of voters “deplorables”. She had virtually nothing to campaign for and chose to attack her opponent with personal smears instead of addressing the issues in the campaign. Why someone like GS who ran a successful campaign to unseat an incumbent doesn’t get it should be surprising, except it’s clear that they all put themselves in a bubble and still can’t get out of it.
Hillary ran her campaign like a shake-down operation, not as an effort to earn votes.
She really slacked off in the last stages of the election.
And, people complete ignored what they were seeing. We saw it! Trump was getting massive crowds. She was getting smaller and smaller groups with her seating downsized.
