I’m no Berner but I still blame Clinton. She was the candidate and it was her job to win. She didn’t. Strong Democratic areas underperformed, notably SE Pennsylvania. I don’t blame the media because everybody knew what they were getting with Donald Trump. Clinton was solidly ahead on the polls and won the total vote handily. Problem was the votes that really mattered went to Trump. FWIW I also blame Kerry for losing in 2004. His campaign had such a tepid response to the Swiftboaters and as I remember that really was the factor in W’s win.
BTW, I have been hard on Hilary Clinton. For the record I never, EVER, engaged in the right’s smear campaign. In my eyes she was a terrific SoS (I’ll come back to that with an aside about the State Dept. later) and Senator. In my eyes failure is the responsibility of the boss. I don’t care if my press operator’s wife ran away with his best buddy and took his dog, and the trimmer’s allergies are in full bloom and the shipper is distracted by shiny objects. If bad parts made it out the door, it was my fault. When we closed in 2012, there were a million reasons, but none of them insurmountable. It was my fault my employees lost their jobs. The same goes for Clinton. There were many factors in the result of the campaign, but none of them were insurmountable.
