Exit polls from 4 key states had Clinton winning but it is quite possible this is all over my head…

What you’re saying makes sense. I can see two credible hypotheses: Trump voters lied to pollsters out of embarrassment; and people who made up their minds at the last minute were swayed by late-breaking news — more precisely, stories. It’s reasonable to guess that both hypotheses have some truth. In any event, Clinton was a fragile candidate because she didn’t offer an involving story.
