As a younger man I would have been with the commenters mansplaining probability, but I've aged into realizing that thinking of the election like a marble pulled from an urn whose contents we have probed with polling is just as bad as thinking of it as deterministic. The reason people read fivethirtyeight, probability-savvy or not, was almost entirely to be told what was going to happen, which is sort of incompatible with feeling you can do anything about it. In that way it's probably worse than old-fashioned pundit-driven horse race coverage because it has an air of scientific authority.
